Your Remote Access VPN May Need a Security Check After Recent Exploited Flaws

Remote access is convenient, but it must be maintained

Remote access tools help employees work from home, connect from the road, and reach business systems after hours. For many small businesses, a VPN acts like a private doorway into the office network.

That doorway needs regular maintenance.

In June 2026, CISA added a Check Point Security Gateway vulnerability, CVE-2026-50751, to its Known Exploited Vulnerabilities catalog. Security reporting from Rapid7 also noted active exploitation beginning in May 2026, with activity increasing in early June. The technical details are complex, but the business takeaway is simple: some remote access systems can become risky very quickly when old settings or unpatched equipment are still in use.

Why this matters to small businesses

A VPN is supposed to help keep outsiders out. If attackers can abuse a weakness in the remote access system, they may be able to get closer to internal business systems without tricking an employee first.

For a small business, that can put several things at risk:

• Shared files and customer records
• Accounting systems and payment workflows
• Email and Microsoft 365 access
• Point-of-sale or scheduling systems
• Server backups and business applications

This does not mean every VPN is unsafe. It does mean business owners should not assume the firewall or VPN is “set it and forget it.”

The plain-English problem: old access methods create open doors

Many businesses keep older VPN settings because they still work. The problem is that “still works” is not the same as “still safe.”

Older firewall versions, outdated VPN clients, legacy authentication settings, and unsupported equipment can create security gaps. Attackers often look for these gaps because they know many small businesses do not review firewall settings unless something breaks.

That is why remote access should be treated like a business-critical system, not just a convenience.

What small businesses should do now

Start with a practical review:

• Confirm what firewall or VPN product your business uses.
• Check whether the device is still supported by the vendor.
• Make sure security updates and hotfixes are installed.
• Disable old remote access methods that are no longer needed.
• Require strong login protection for remote users.
• Review who still has VPN access, especially former employees or vendors.
• Check logs for unusual access, especially after a known vulnerability is announced.
• Document who is responsible for firewall updates and emergency patches.

For many business owners, the most important question is not “Do we have a VPN?” It is “Who is actively watching and maintaining it?”

Do not wait for the regular update cycle

Security updates for office computers can often follow a normal schedule. Firewall and VPN issues are different. When a remote access flaw is actively exploited, waiting weeks can leave the front door exposed.

If your business depends on remote access, your IT team or provider should have a clear process for urgent firewall reviews, vendor advisories, emergency patches, and after-the-fact log checks.

The bigger lesson

Remote work is now normal. Cloud apps are normal. Vendor access is normal. That means remote access security has to be normal too.

Small businesses do not need enterprise-level complexity, but they do need the basics done consistently: supported equipment, current patches, clean access lists, strong authentication, and someone paying attention when major advisories are released.

Cybernetic Networks helps Orlando-area small businesses review firewalls, VPN access, remote work security, and ransomware prevention in plain business terms. If you are not sure whether your remote access setup is current, supported, or being monitored, our team can help you check it before a small configuration issue becomes a business interruption.
