Source: Google Mandiant, 2024. "Now" is our estimate: AI models like Claude Mythos can find and chain new vulnerabilities in hours.
AI just found thousands of zero-days.
In April 2026, Anthropic previewed Claude Mythos, an AI model that found thousands of serious security flaws nobody knew about. Some had been hiding for decades in software that runs most of the world's computers.
Anthropic kept the model private and gave a small group of large companies time to patch. Tools like it will reach attackers eventually. When they do, every unpatched system gets easier to break into, and small businesses are the easiest of all.

- how long one OpenBSD bug went unnoticed before the model found it
- organizations given early access to patch first, including AWS, Apple, Google and Microsoft
What it means for a 50-person company
Old software is a liability
Bugs that hid for years will surface fast. Anything you run but don't update is now a target.
Patch in days, not quarters
Attackers used new vulnerabilities within five days on average in 2023, and AI is shrinking that further. Monthly patching isn't enough for anything on the internet.
Defenders get AI too
We use AI-assisted tools to find weaknesses in your systems first, and people who know how to fix them without breaking your business.
Are you ready for the next zero-day?
Six questions, about a minute. Your answers stay in your browser unless you send them with a review request.
Answer all six to see your score.
"Not sure" counts as a gap. If you can't confirm it, an attacker may find out first.
The portfolio
Start with one tool or hand us the whole job. Every piece works on its own and with the rest.

Zero-Day Alerts
Matches newly exploited vulnerabilities against the software you actually run and tells you within hours, with the fix.
Good for: Patching what matters before it's used against you
DMARC Monitor
Shows every service sending email as your domain, then walks you to a policy that blocks impersonators.
Good for: Stopping fake invoices and spoofed email
Phishing Simulator

How we work
The same three steps whether you start with one tool or a full solution.
Assess
A free 30-minute review, then a full scan of what you have on the internet. You see every risk ranked by how likely it is to be used against you.
Fix
We close the most dangerous gaps first, with you or your IT provider, and show you exactly what changed.
Protect
Monitoring and zero-day alerts keep it that way. Each month you get a short report in plain language.
How we treat your business
- Plain language
- Every report says what's wrong, why it matters and what to do first.
- Only the access we need
- We ask for the smallest set of permissions for the job, and you can revoke them at any time.
- We work with your IT team
- Already have an IT provider? We fill the security gaps and leave the day-to-day with them.
- Your data stays yours
- We never sell your data or use it to train AI models. When we part ways, we hand everything back.
Questions
Something else on your mind? Ask it in your review request.
What is a zero-day?
A security flaw that attackers can use before the software maker has released a fix. The name comes from the number of days defenders have had to prepare: zero.
Does AI really change anything for a small business?
Yes. Most attacks are automated and don't care about company size. AI makes it cheaper to find new flaws and to aim them at thousands of businesses at once. The same tools help us find your weaknesses first.
Do you use Claude Mythos?
No. Anthropic has limited Mythos to a small group of large organizations. We use commercially available AI tools alongside experienced human testers.
Do you replace our IT provider?
No. We handle security and work alongside whoever runs your IT today.
