The MFA Level-Up: Why SMS Codes Are No Longer Enough (and What to Use Instead)

For years, enabling Multi-Factor Authentication (MFA) has been a cornerstone of account and device security. While MFA remains essential, the threat landscape has evolved, making some older methods less effective.

The most common form of MFA, four- or six-digit codes sent via SMS, is convenient and familiar, and it’s certainly better than relying on passwords alone. However, SMS is an outdated technology, and cybercriminals have developed reliable ways to bypass it. For organizations handling sensitive data, SMS-based MFA is no longer sufficient. It’s time to adopt the next generation of phishing-resistant MFA to stay ahead of today’s attackers.

SMS was never intended to serve as a secure authentication channel. Its reliance on cellular networks exposes it to security flaws, particularly in telecommunication protocols such as Signaling System No. 7 (SS7), used for communication between networks.

Attackers know that many businesses still use SMS for MFA, which makes them appealing targets. For instance, hackers can exploit SS7 vulnerabilities to intercept text messages without touching your phone. Techniques such as eavesdropping, message redirection, and message injection can be carried out within the carrier network or during over-the-air transmission.

SMS codes are also vulnerable to phishing. If a user enters their username, password, and SMS code on a fake login page, attackers can capture all three in real time and immediately gain access the legitimate account.

Understanding SIM Swapping Attacks

One of the most dangerous threats to SMS-based security is the SIM swap. In SIM swapping attacks, a criminal contacts your mobile carrier pretending to be you and claims to have lost their phone. They then request the support staff to port your number to a new blank SIM card in their possession.

If they succeed, your phone goes offline, allowing them to receive all calls and SMS messages, including MFA codes for banking and email. Without knowing your password, they can quickly reset credentials and gain full access to your accounts.

This attack doesn’t depend on advanced hacking skills; instead, it exploits social engineering tactics against mobile carrier support staff, making it a low-tech method with high‑impact consequences.

Why Phishing-Resistant MFA Is the New Gold Standard

To prevent these attacks, it’s essential to remove the human element from authentication by using phishing-resistant MFA. This approach relies on secure cryptographic protocols that tie login attempts to specific domains.

One of the more prominent standards used for such authentication is Fast Identity Online 2 (FIDO2) open standard, that uses passkeys created using public key cryptography linking a specific device to a domain. Even if a user is tricked into clicking a phishing link, their authenticator application will not release the credentials because the domain does not match the specific record. 

The technology is also passwordless, which removes the threat of phishing attacks that capture credentials and one-time passwords (OTPs). Hackers are forced to target the endpoint device itself, which is far more difficult than deceiving users.

Implementing Hardware Security Keys

Perhaps one of the strongest phishing-resistant authentication solutions involves hardware security keys. Hardware security keys are physical devices resembling a USB drive, which can be plugged into a computer or tapped against a mobile device.

To log in, you simply insert the key into the computer or touch a button, and the key performs a cryptographic handshake with the service. This method is quite secure since there are no codes to type, and attackers can’t steal your key over the internet. Unless they physically steal the key from you, they cannot access your account.

Mobile Authentication Apps and Push Notifications

If physical keys are not feasible for your business, mobile authenticator apps such as Microsoft or Google Authenticator are a step up from SMS MFA. These apps generate codes locally on the device, eliminating the risk of SIM swapping or SMS interception since the codes are not sent over a cellular network.

Simple push notifications also carry risks. For example, attackers may flood a user’s phone with repeated login approval requests, causing “MFA fatigue,” where a frustrated or confused user taps “approve” just to stop the notifications. Modern authenticator apps address this with “number matching,” requiring the user to enter a number shown on their login screen into the app. This ensures the person approving the login is physically present at their computer.

Passkeys: The Future of Authentication

With passwords being routinely compromised, modern systems are embracing passkeys, which are digital credentials stored on a device and protected by biometrics such as fingerprint or Face ID. Passkeys are phishing-resistant and can be synchronized across your ecosystem, such as iCloud Keychain or Google Password Manager. They offer the security of a hardware key with the convenience of a device that you already carry. 

Passkeys reduce the workload for IT support, as there are no passwords to store, reset, or manage. They simplify the user experience while strengthening security.

Balancing Security With User Experience

Moving away from SMS-based MFA requires a cultural shift. Since users are already used to the universality and convenience of text messages, the introduction of physical keys and authenticator apps can trigger resistance. 

It’s important to explain the reasoning behind the change, highlighting the realities of SIM-swapping attacks and the value of the protected information. When users understand the risks, they are more likely to embrace the new measures.

While a phased rollout can help ease the transition for the general user base, phishing-resistant MFA should be mandatory for privileged accounts. Administrators and executives must not rely on SMS-based MFA.

The Costs of Inaction

Sticking with legacy MFA techniques is a ticking time bomb that gives a false sense of security. While it may satisfy compliance requirements, it leaves systems vulnerable to attacks and breaches, which can be both costly and embarrassing. 

Upgrading your authentication methods offers one of the highest returns on investment in cybersecurity. The cost of hardware keys or management software is minimal compared to the expense of incident response and data recovery.

Securing the ‘Third Place’ Office: Policy Guidelines for Employees Working from Coffee Shops and Coworking Spaces

The modern office extends far beyond traditional cubicles or open-plan spaces. Since the concept of remote work became popularized in the COVID and post-COVID era, employees now find themselves working from their homes, libraries, bustling coffee shops, and even vacation destinations. These environments, often called “third places,” offer flexibility and convenience but can also introduce risks to company IT systems.

With remote work now a permanent reality, businesses must adapt their security policies accordingly. A coffee shop cannot be treated like a secure office, as its open environment exposes different types of threats. Employees need clear guidance on how to stay safe and protect company data.

Neglecting security on public Wi-Fi can have serious consequences, as hackers often target these locations to exploit remote workers. Equip your team with the right knowledge and tools, and enforce a robust external network security policy to keep company data safe.

The Dangers of Open Networks

Free internet access is a major draw for remote workers frequenting cafes, malls, libraries, and coworking spaces. However, these networks rarely have encryption or strong security, and even when they do, they lack the specific controls that would be present in a secure company network. This makes it easy for cybercriminals to intercept network traffic and steal passwords or sensitive emails in a matter of seconds.

Attackers often set up fake networks that look legitimate. They might give them names such as “Free Wi-Fi” or give them a name resembling a nearby business, such as a coffee shop or café, to trick users. Once connected, the hacker who controls the network sees everything the employee sends. This is a classic “man-in-the-middle” attack.

It is critical to advise employees never to rely on open connections. Networks that require a password may still be widely shared, posing significant risks to business data. Exercise caution at all times when accessing public networks.

Mandating Virtual Private Networks

The most effective tool for remote security is a VPN. A Virtual Private Network encrypts all data leaving the laptop by creating a secure tunnel through the unsecured public internet. This makes the data unreadable to anyone trying to snoop.

Providing a VPN is essential for remote work, and employees should be required to use it whenever they are outside the office. Ensure the software is easy to launch and operate, as overly complex tools may be ignored. Whenever possible, configure the VPN to connect automatically on employee devices, eliminating human error and ensuring continuous protection.

At the same time, enforce mandatory VPN usage by implementing technical controls that prevent employees from bypassing the connection when accessing company servers.

The Risk of Visual Hacking

Digital threats are not the only concern in public spaces since someone sitting at the next table can easily glance at a screen. Visual hacking involves stealing information just by looking over a shoulder, which makes it low-tech but highly effective and hard to trace.

Employees often forget how visible their screens are to passersby, and in a crowded room full of prying eyes, sensitive client data, financial spreadsheets, and product designs are at risk of being viewed and even covertly photographed by malicious actors. 

To address this physical security gap, issue privacy screens to all employees who work remotely. Privacy screens are filters that make laptop and monitor screens appear black from the side, and only the person sitting directly in front can see the content. Some devices come with built-in hardware privacy screens that obscure content so that it cannot be viewed from an angle. 

Physical Security of Devices

Leaving a laptop unattended is a recipe for theft. In a secure office, you might walk away to get water or even leave the office and expect to find your device in the same place, untouched. In a coffee shop, that same action can cost you a device, since thieves are always scanning for distracted victims and are quick to act.

Your remote work policy should stress the importance of physical device security. Employees must keep their laptops with them at all times and never entrust them to strangers. A laptop can be stolen and its data accessed in just seconds.

Encourage employees to use cable locks, particularly if they plan to remain in one location for an extended period. While not foolproof, locks serve as a deterrent, especially in coworking spaces where some level of security is expected. The goal is to make theft more difficult, and staying aware of the surroundings helps employees assess potential risks.

Handling Phone Calls and Conversations

Coffee shops can be noisy, but conversations still travel through the air. Discussing confidential business matters in public is risky, as you never know who might be listening. Competitors or malicious actors could easily overhear sensitive information.

Employees should avoid discussing sensitive matters in these “third places.” If a call is necessary, they should step outside or move to a private space, such as a car. While headphones prevent others from hearing the other side, the employee’s own voice can still be overheard.

Creating a Clear Remote Work Policy

Employees shouldn’t have to guess the rules. A written policy clarifies expectations, sets standards, and supports training and enforcement.

Include dedicated sections on public Wi-Fi and physical security, and explain the reasoning behind each rule so employees understand their importance. Make sure the policy is easily accessible on the company intranet.

Most importantly, review this policy annually as technology changes. As new threats emerge, your guidelines must also evolve to counter them. Make routine updates to the policy, and reissue the revised versions to keep the conversation about security alive and ongoing.

Empower Your Remote Teams

While working from a “third place” offers flexibility and a morale boost, it also requires a higher level of vigilance. This makes prioritizing public Wi-Fi security and physical awareness non-negotiable, and you must equip your team to work safely from anywhere.

With the right tools and policies, you can manage the risks while enjoying the benefits of remote work. Success comes from balancing freedom with responsibility, and well-informed employees serve as your strongest line of defense. Protect your data, no matter where your team works.

Is your team working remotely without a safety net? We help businesses implement secure remote access solutions and policies, ensuring your data stays private, even on public networks. Call us today to fortify your remote workforce.

How to Implement Zero Trust for Your Office Guest Wi-Fi Network

Guest Wi-Fi is a convenience your visitors expect and a hallmark of good customer service. But it’s also one of the riskiest points in your network. A shared password that’s been passed around for years offers virtually no protection, and a single compromised guest device can become a gateway for attacks on your entire business. That’s why adopting a Zero Trust approach for your guest Wi-Fi is essential.

The core principle of Zero Trust is simple but powerful: never trust, always verify. No device or user gains automatic trust just because they’re on your guest network. Here are some practical steps to create a secure and professional guest Wi-Fi environment.

Business Benefits of Zero Trust Guest Wi-Fi

Implementing a Zero Trust guest Wi-Fi network is not just a technical necessity; it’s a strategic business decision that delivers clear financial and reputational benefits. By moving away from a risky shared password system, you significantly reduce the likelihood of costly security incidents. A single compromised guest device can act as a gateway for attacks on your entire business , leading to devastating downtime, data breaches, and regulatory fines. The proactive measures of isolation, verification, and policy enforcement are an investment in business continuity.

Consider the Marriott data breach where attackers gained access to their network through a third-party access point, eventually compromising the personal information of millions of guests. While not specifically a Wi-Fi breach, it serves as a stark reminder of the massive financial and reputational damage caused by an insecure network entry point. A Zero Trust guest network, which strictly isolates guest traffic from corporate systems, would prevent this lateral movement and contain any threat to the public internet.

Build a Totally Isolated Guest Network

The first and most crucial step is complete separation. Your guest network should never mix with your business traffic. This can be achieved through strict network segmentation by setting up a dedicated Virtual Local Area Network (VLAN) for guests. This guest VLAN should run on its own unique IP range, entirely isolated from your corporate systems.

Then, configure your firewall with explicit rules that block all communication attempts from the guest VLAN to your primary corporate VLAN. The only destination your guests should be able to reach is the public internet. This strategic containment ensures that if a guest device is infected with malware, it cannot pivot laterally to attack your servers, file shares, or sensitive data.

Implement a Professional Captive Portal

Get rid of the static password immediately. A fixed code is easily shared, impossible to track, and a hassle to revoke for just one person. Instead, implement a professional captive portal, like the branded splash page you encounter when connecting to Wi-Fi at a hotel or conference. This portal serves as the front door to your Zero Trust guest Wi-Fi.

When a guest tries to connect, their device is redirected to the portal. You can configure it securely in several ways. For example, a receptionist could generate a unique login code that expires in 8 or 24 hours, or visitors could provide their name and email to receive access. For even stronger security, a one-time password sent via SMS can be used. Each of these methods enforces the ‘never trust’ principle, turning what would be an anonymous connection into a fully identified session.

Enforce Policies via Network Access Control

Having a captive portal is a great start, but to achieve true guest network security, you need more powerful enforcement, and that is where a Network Access Control (NAC) solution comes into play. NAC acts like a bouncer for your network, checking every device before it is allowed to join, and you can integrate it within your captive portal for a seamless yet secure experience.

A NAC solution can be configured to perform various device security posture checks, such as verifying whether the connecting guest device has a basic firewall enabled or whether it has the most up-to-date system security patches. If the guest’s device fails these posture checks, the NAC can redirect it to a walled garden with links to download patch updates or simply block access entirely. This proactive approach prevents vulnerable devices from introducing risks into your network. 

Apply Strict Access Time and Bandwidth Limits 

Trust isn’t just about determining who is reliable, it’s about controlling how long they have access and what they can do on your network. A contractor doesn’t need the same continuous access as a full-time employee. Use your NAC or firewall to enforce strict session timeouts, requiring users to re-authenticate after a set period, such as every 12 hours.

Similarly, implement bandwidth throttling on the guest network. In most cases, a guest only needs basic internet access to perform general tasks such as reading their emails and web browsing. This means limiting guest users from engaging in activities such as 4K video streaming and downloading torrent files that use up the valuable internet bandwidth needed for your business operations. While these limitations may seem impolite, they are well in line with the Zero Trust principle of granting least privilege. It is also a good business practice to prevent network congestion by activities that do not align with your business operations.

Create a Secure and Welcoming Experience

Implementing a Zero Trust guest Wi-Fi network is no longer an advanced feature reserved for large enterprises, but a fundamental security requirement for businesses of all sizes. It protects your core assets while simultaneously providing a professional, convenient service for your visitors. The process hinges on a layered approach of segmentation, verification, and continuous policy enforcement, and effectively closes a commonly exploited and overlooked network entry point.

The Hidden Risk of Integrations: A Checklist for Vetting Third-Party Apps (API Security)

Modern businesses depend on third-party apps for everything from customer service and analytics to cloud storage and security. But this convenience comes with risk, every integration introduces a potential vulnerability. In fact, 35.5% of all recorded breaches in 2024 were linked to third-party vulnerabilities. 

The good news? These risks can be managed. This article highlights the hidden dangers of third-party API integrations and provides a practical checklist to help you evaluate any external app before adding it to your system.

Why Third-Party Apps Are Essential in Modern Business 

Simply put, third-party integrations boost efficiency, streamline operations, and improve overall productivity. Most businesses do not create each technology component from scratch. Instead, they rely on third-party apps and APIs to manage everything from payments to customer support, analytics, email automation, chatbots, and more. The aim is to speed up development, cut costs, and gain access to features that might take months to build internally. 

What Are the Hidden Risks of Integrating Third-Party Apps? 

Adding third-party apps to your systems invites several risks, including security, privacy, compliance, and operational and financial vulnerabilities.

Security Risks

Third-party integrations can introduce unexpected security risks into your business environment. A seemingly harmless plugin may contain malware or malicious code that activates upon installation, potentially corrupting data or allowing unauthorized access. Once an integration is compromised, hackers can use it as a gateway to infiltrate your systems, steal sensitive information, or cause operational disruptions.

Privacy and Compliance Risks

Even with strong contractual and technical controls, a compromised third-party app can still put your data at risk. Vendors may gain access to sensitive information and use it in ways you never authorized, such as storing it in different regions, sharing it with other partners, or analyzing it beyond the agreed purpose. For instance, misuse of a platform could lead to violations of data protection laws, exposing your organization to legal penalties and reputational damage.

Operational and Financial Risks

Third-party integrations can affect both operations and finances. If an API fails or underperforms, it can disrupt workflows, cause outages, and impact service quality. Weak credentials or insecure integrations can be exploited, potentially leading to unauthorized access or costly financial losses.

What to Review Before Integrating a Third-Party API 

Before you connect any app, take a moment to give it a careful check-up. Use the checklist below to make sure it’s safe, secure, and ready to work for you.

  1. Check Security Credentials and Certifications: Make sure the app provider has solid, recognized security credentials, such as ISO 27001, SOC 2, or NIST compliance. Ask for audit or penetration test reports and see if they run a bug bounty program or have a formal vulnerability disclosure policy. These show the vendor actively looks for and addresses security issues before they become a problem.
  2. Confirm Data Encryption: You might not be able to inspect a third-party app directly, but you can review their documentation, security policies, or certifications like ISO 27001 or SOC. Ask the vendor how they encrypt data both in transit and at rest, and make sure any data moving across networks uses strong protocols like TLS 1.3 or higher.
  3. Review Authentication & Access: Make sure the app uses modern standards like OAuth2, OpenID Connect, or JWT tokens. Confirm it follows the principle of least privilege, giving users only the access they truly need. Credentials should be rotated regularly, tokens kept short-lived, and permissions strictly enforced.
  4. Check Monitoring & Threat Detection: Look for apps that offer proper logging, alerting, and monitoring. Ask the vendor how they detect vulnerabilities and respond to threats. Once integrated, consider maintaining your own logs to keep a close eye on activity and spot potential issues early.
  5. Verify Versioning & Deprecation Policies: Make sure the API provider maintains clear versioning, guarantees backward compatibility, and communicates when features are being retired.
  6. Rate Limits & Quotas: Prevent abuse or system overload by confirming the provider supports safe throttling and request limits.
  7. Right to Audit & Contracts: Protect yourself with contractual terms that allow you to audit security practices, request documentation, and enforce remediation timelines when needed.
  8. Data Location & Jurisdiction: Know where your data is stored and processed, and ensure it complies with local regulations.
  9. Failover & Resilience: Ask how the vendor handles downtime, redundancy, fallback mechanisms, and data recovery, because no one wants surprises when systems fail.
  10. Check Dependencies & Supply Chain: Get a list of the libraries and dependencies the vendor uses, especially open-source ones. Assess them for known vulnerabilities to avoid hidden risks.

Vet Your Integrations Today 

No technology is ever completely risk-free, but the right safeguards can help you manage potential issues. Treat third-party vetting as an ongoing process rather than a one-time task. Continuous monitoring, regular reassessments, and well-defined safety controls are essential.

How to Use a Password Manager and Virtual Cards for Zero-Risk Holiday Shopping

Have you ever been concerned about your credit card or personal data getting stolen while shopping online? You’re not alone. Each holiday season, as millions of shoppers flock online for convenience, hackers ramp up their activity. The Federal Trade Commission (FTC) has warned that scammers often create fake shopping websites or phishing emails to steal consumers’ money and personal information, especially during the holidays.

If you’re planning to shop this holiday season, now is the perfect time to boost your online security. Two simple tools, password managers and virtual cards, can make a big difference. But how exactly? This article will show you how to use them to enjoy zero-risk online holiday shopping.

Why People Prefer Password Managers and Virtual Cards for Online Shopping

Shopping online is quick, easy, and often cheaper than going to physical stores. However, it is fraught with security risks. Many people now use password managers and virtual cards for safer transactions. 

A password manager creates and keeps complicated, distinct passwords for all accounts. This minimizes the chance of unauthorized access and theft. The Cybersecurity and Infrastructure Security Agency (CISA) recommends using password managers to reduce password reuse and protect sensitive data from hackers.

Virtual cards also add an extra layer of protection when shopping online. Although the card numbers are linked to your real credit or debit card account, the merchant never sees your card details. This helps prevent identity theft and financial fraud.

Tips for Using Password Managers and Virtual Cards for Zero-Risk Holiday Shopping

Before you start adding items to your cart, the safety of your money comes first. Here are smart ways to use these tools to improve online security during the holidays.

Choose a Reputable Password Manager

Select a trusted provider with strong encryption and a solid reputation. Popular options include 1Password, Dashlane, LastPass, and Bitwarden. Fake versions are everywhere, so make sure you only download from the official website or app store.

Create a Strong Master Password

Your master password protects all your other passwords and should be the most secure. “Secure” means making it unusual and not something that can be guessed. You can achieve this by combining letters, numbers, and special characters. 

Turn On Two-Factor Authentication (2FA)

2FA adds another protection step by requiring two verification steps. Besides your password, you can choose to receive a verification code on your phone. Even if hackers steal your password, they can’t access your account without your verification code.

Generate Virtual Cards for Each Store

Set up a separate virtual card for each online retailer, many banks and payment apps offer this feature. That way, if one store is compromised, only that temporary card is affected, your main account stays safe.

Track Expiration Dates and Spending Limits

Virtual cards often expire after a set time or after one purchase. This is good for security, but make sure your card is valid before placing an order. Set spending limits as well, as this helps with holiday budgeting and prevents unauthorized charges.

Shop Only on Secure Websites

Be sure to purchase only from websites you are familiar with. Don’t shop from any link in an advertisement or email. You may end up on phishing sites that target your information. The URL of a safe site starts with “https://.”

Also, pay attention to data encryption. Look for the padlock symbol on your browser address bar. This indicates that the site has employed SSL/TLS encryption, which encrypts data as it is passed between your device and the site.

Common Mistakes to Avoid for Safer Online Shopping

Even with the best security tools, simple mistakes can put your data at risk. Developing strong security awareness is key to safer online habits. Here are some common pitfalls to watch out for when shopping:

Reusing Passwords

One hacked password can put all your accounts at risk. Keep them safe by using a different password for every site, your password manager makes it easy.to generate and store strong, distinct passwords for each one.

Using Public Wi-Fi for Shopping

Hackers can easily monitor public Wi-Fi networks, making them unsafe not just for shopping but for any online activity. To protect your data, avoid using Wi-Fi in coffee shops, hotels, or airports for online shopping. Instead, stick to your mobile data or a secure private network.

Ignoring Security Alerts

Many people overlook alerts about unusual activity but ignoring them can be risky. If your bank, password manager, or virtual card provider alerts you to suspicious activity, act immediately. Follow their instructions to protect your data, for example, changing your password and reviewing recent transactions for any signs of fraud.

Saving Card Details in Your Browser

While browsers allow card information to be saved, it is less secure than virtual cards. If hackers access your browser, your saved cards are compromised.

Shop Smarter and Safer This Holiday Season

The holidays should be about celebration, not about worrying over hacked accounts or stolen card details. Using tools like password managers and virtual cards lets you take control of your online shopping security. These tools make password management easier, protect you from phishing scams, and add extra protection against cybercriminals. As you look for the best holiday deals, include security in your shopping checklist. Peace of mind is the best gift you can give yourself.
