CISA Cyber Assessments End: Protect Your Communications

Your critical infrastructure organization just lost access to free cybersecurity assessments from CISA—and that’s a problem. For years, public safety agencies, utilities, transportation departments, and healthcare systems relied on these evaluations to identify communication vulnerabilities. Now that support is gone, and critical infrastructure cybersecurity falls entirely on your team. The good news? You don’t have to start from scratch. Understanding the gap and taking immediate steps to secure your communications systems can protect your organization from costly breaches.

What Happened to CISA’s Free Assessment Program

The Cybersecurity and Infrastructure Security Agency (CISA) recently discontinued its free vulnerability assessment and scanning services for critical infrastructure organizations. These assessments were designed to help agencies across multiple sectors—including emergency services, power grids, water utilities, transportation networks, and hospitals—evaluate their security posture without expensive consulting fees.

This program was especially valuable for smaller jurisdictions and rural agencies that lacked dedicated cybersecurity budgets. Without CISA’s support, these organizations now face a difficult choice: hire external security consultants, build internal capabilities, or operate with gaps in their security knowledge.

Because of this change, many agencies are scrambling to fill the void. The transition creates both risk and opportunity—risk because vulnerabilities may go undetected, but opportunity because organizations can now take control of their own security strategies, starting with their communications infrastructure.

What This Means for Critical Infrastructure Organizations

For emergency responders, utility workers, transportation crews, and healthcare coordinators, secure communications aren’t optional—they’re essential. Your two-way radios carry sensitive information: dispatch locations, patient conditions, power outage reports, and incident details. If your communication channels aren’t secure, that information is exposed.

The loss of CISA assessments means your organization must now independently evaluate communication vulnerabilities. That includes checking whether your radios use encryption, whether your network supports interoperability standards, and whether your systems can withstand physical and cyber threats. For many agencies, this represents a significant responsibility shift.

The real impact hits hardest when you consider response times and operational continuity. A compromised radio network doesn’t just expose data—it can disrupt emergency response, delay critical operations, and put personnel at risk. Without CISA’s help identifying these risks, agencies need a new approach to communication security.

How Two-Way Radios Address This Challenge

Secure two-way radio systems are foundational to protecting critical infrastructure communications. Modern LMR (Land Mobile Radio) systems, especially those built on P25 digital standards, include layered security features that address vulnerabilities CISA assessments used to identify.

Here’s what makes modern radio systems more secure:

• End-to-end encryption scrambles voice and data so only authorized personnel can listen in
• P25 digital protocol compliance ensures interoperability with other agencies while maintaining security standards
• Authentication controls prevent unauthorized users from accessing the network
• Redundant networks and failover keep communications running even if one path is compromised
• Physical durability protects equipment from intentional or accidental damage

Unlike consumer or internet-based communication tools, two-way radios don’t rely on cloud infrastructure or public networks. That means your emergency dispatch, field teams, and critical operations stay off the public internet—automatically reducing exposure to many cyber threats. When you add encryption, the protection becomes even stronger.

For organizations looking to bridge the gap left by CISA’s program, upgrading to a modern [LINK: P25 digital radio systems or secure LMR networks] is one of the highest-impact steps you can take. You gain not just security, but also reliability, range, and the ability to coordinate with other agencies during emergencies.

Common Questions About Radio Security

Q: Do we really need encryption on our radios?
A: If your communications contain any sensitive information—dispatch details, patient data, operational status, or emergency response tactics—encryption is essential. Modern P25 digital systems make encryption standard and transparent to users.

Q: What’s the difference between P25 and older analog systems?
A: Analog radios transmit voice as radio waves anyone can hear with a scanner. P25 digital systems offer encryption, better audio quality, more capacity, and built-in security features. For critical infrastructure, the upgrade is a major step forward.

Q: Is upgrading radio systems expensive?
A: Costs vary based on fleet size, coverage area, and features you need. Many agencies find that the security and operational benefits justify the investment, and options exist for different budgets.

Take Control of Your Communications Security

With CISA assessments no longer available, your critical infrastructure organization has an opportunity to take ownership of your communications security. The first step is honest evaluation: Are your current radios encrypted? Do they meet P25 standards? Are your teams coordinating on secure channels?

If you’re uncertain about any of these questions, now is the time to act. Waiting puts your operations and personnel at risk. Two-way radio systems designed for critical infrastructure provide the foundation you need to operate securely and reliably, even without external assessments.
