I wasn’t going to write about Mythos or AI security right away. I wanted to let the noise settle before I added to it. The last thing I wanted was to pile on with another “cybersecurity is over” take, or worse, sound like one of the vendors using this moment to sell you something.

So, I waited. Here’s my actual take…

Let Me Be Direct

There’s a lot of hype and some of it is warranted. But cybersecurity isn’t over. It’s being forced to evolve and what’s changing is how fast the game moves.

What worries me more than Mythos itself is how people are reacting to it. Two camps are forming, and neither ends well.

The first is the overreactors. Potentially panic-buying every AI security tool that shows up, throwing budget at whoever is loudest, because the board is asking questions and something has to be done. The “cybersecurity is over” narrative is convenient for the vendors selling the replacement. If you’re tired of vendors pushing tools and calling it strategy, you’re not alone. That’s not a strategy.

The second might actually be more dangerous. These are the people writing it off entirely. Assuming it’s all hype and their current posture is fine. The adversaries aren’t being dismissive, and when those organizations finally feel it, they’ll be completely flat-footed.

Both extremes leave you exposed.

What Actually Changes

Vulnerabilities will be discovered faster than ever. Attack paths that used to require serious expertise can now be strung together by people who never could have done it before. AI lowers the barrier to entry, but it amplifies capability too. A skilled attacker with these tools isn’t just faster, they’re operating at a different level entirely.

But the same speed applies to defenders. For the first time, security teams have a real edge at the build and development phase. Shifting left finally means something.

The gap that matters is the time-to-patch window. AI can find a vulnerability fast, but remediation is still human speed. The vendor has to build the patch. You have to test it, validate it, deploy it. All while trying to not to slow down the business. Attackers aren’t waiting.

Three Facts Worth Holding Onto

Before getting to the action items, three things are worth keeping in mind. They’re the context every security leader and board member needs before turning this into strategy, budget, or panic.

1. There’s a Need for Fast, Coordinated Decision-Making at Scale

Inventory, identity, patching, segmentation. The fundamentals haven’t changed. What’s changed is how unforgiving the timeline is when you don’t have them in place. During an incident, there needs to be clear decision makers and communication paths. Measuring decision making speed is now just as important as Mean Time to Detection & Remediation.

2. The AI Advantage Cuts Both Ways

Attackers get faster. Defenders get faster. The advantage goes to whoever was already prepared to use the speed. The winners will not be the teams with the most AI tools. They’ll be the teams with the fewest delays between signal, decision, and action.

3. Time-to-Patch Is an Issue

Tools like Mythos may find vulnerabilities faster, but they are not inventing an entirely new class of risk. The flaws still look familiar; what changes is how quickly organizations need to validate, prioritize, and fix them.. Your remediation pipeline has to close that gap, or it gets closed for you.

What You Need To Focus On

These aren’t headline-grabbing recommendations. But they’re what actually matters the most right now.

Know your attack surface. Keep a continuous, updated inventory of everything public facing. If you don’t know what’s out there, nothing else you do will save you.

Identity remains the front door. Attackers will take the easiest way in. They still need an identity to move, escalate, and persist. Ensuring complete MFA coverage alongside phish-resistant MFA, least privilege, just-in-time access, and Conditional Access with real purpose. Build a behavioral baseline so you know when something stops looking normal.

And don’t underestimate where phishing is heading. AI-generated phishing held under 5% of attacks per month for the first 11 months of 2025, then surged to 56% in December during the holiday season and settled at 40% in January 2026*. These aren’t the clunky, obvious emails your users learned to spot. They’re personalized, polished, and getting harder to catch. Your security awareness training needs to keep pace with that reality.

Non-human identities (NHI) are the blind spot. AI agents, cloud workload identities, service accounts, API connections. Most are privileged. Most aren’t monitored. If your identity program was built around managing people, it wasn’t built for this. This is an investment to think about sooner rather than later.

Enhance your patching process. The 30 and 60 day windows are done. Build the ability to test and deploy faster. Take away the business’s excuse about potential disruption. You’ll need a realistic internal look at where patches are getting stuck and why. Have an emergency patching process documented before you need it, not during an incident.

Be ready for when something gets through. You’ve tightened your inventory, locked down identity, and accelerated patching. But you still need to ask whether your network is segmented in a way that stops ransomware from spreading everywhere, whether your backups are truly immutable and out of reach, whether you have 24/7 SOC coverage and a rehearsed IR plan, and whether the business can survive a cyber event while you recover.

If any of those answers is no, maybe, or not sure, that’s your homework. These weren’t weaknesses Mythos created. They were already there. AI and Mythos just raised the cost of ignoring them.

Final Thought

New tools will keep coming, each promising to solve your AI security problem. Remember when every vendor had a one-stop Zero Trust solution? That wasn’t true then and this won’t be true now.

Security has always been layered and tried to do more with less. That isn’t changing. We’ll need to be smart with our investments and build a strong short and long-term strategy that makes us more resilient than we are today.

Attackers will gain speed. But we’ll adapt, new defenses will emerge, and cybersecurity will remain as necessary as it was before any of this.

The threat is real. The panic is optional.
