AI-powered attacks are here. Runtime is the only answer.

AI-powered attacks don't wait for your stack to catch up.
Neither does Silverfort.

Models like Anthropic's Mythos can achieve full domain compromise in hours—moving through identity, before detection fires a single signal. Silverfort enforces controls at the moment of authentication, across every identity, before access is granted. Talk to one of our Identity Security Advisors to see how to:

"Silverfort is phenomenal. It blocked Mythos' attempts to spread in the network. At some point we had to disable Silverfort's defenses to allow further testing."

See why Silverfort is the only platform that stops AI-speed attacks at the identity layer

Runtime enforcement across every identity

Silverfort evaluates every access request and applies adaptive controls inline, based on risk. Step up authentication with MFA or JIT access, block risky access, fence service accounts, limit privileged access, and control AI agent activities.

No response window required

Silverfort acts before access is granted, not after an alert is triaged. Block, challenge, or restrict risky access before lateral movement begins and blast radius expands.

Coverage where attackers actually move

Service accounts. NTLM. Legacy applications. OT environments. These are the paths EDR can't see and static PAM doesn't cover. Silverfort enforces controls there too, with no changes to servers, applications, or user behavior.

AI agents secured as first-class identities

AI agents are treated with the same rigor as human identities. Their actions are monitored, their access is protected, and their behavior can be controlled at runtime through native integrations with leading agentic platforms and an MCP gateway.

Dynamic decisions, not static rules

Static policies can't anticipate every path an AI model will construct. Silverfort evaluates every access request dynamically and at runtime, based on real-time behavioral context and risk scoring.

Protection without disruption

Silverfort integrates natively into existing authentication flows with no proxies, network redesigns, application changes, or disruptive infrastructure projects.

"Oh s#$t! We need to shut down Silverfort because we can't run the drill."

On Silverfort preventing a Mythos-based red team exercise

Secure identity when it matters most

Most Identity Security solutions protect where identity is stored, but attackers exploit where identity is used. If enforcement doesn’t happen at runtime, risk turns to reality in seconds. That’s the gap Silverfort closes.

Common questions about Mythos and runtime Identity Security

What is Anthropic's Mythos and why does it matter for enterprise security?

Mythos is a frontier AI model built for autonomous cybersecurity research. In practice, it can execute complete enterprise attack chains at machine speed: reconnaissance, lateral movement, privilege escalation, and data exfiltration, without the delays or mistakes that slow human attackers. This is a qualitative shift in the threat landscape, not just a faster version of existing attacks.

Why can't detection tools like XDR and SIEM stop AI-powered attacks?

Detection tools were designed for a world where attackers move at human speed, where there’s time to generate an alert, triage it, and respond. AI-powered attacks compress that window to minutes. By the time detection fires, the attack may already be complete. Detection still matters. But it can’t be your primary control layer anymore. Runtime Identity Security fills that gap. By enforcing controls inline, at the moment of every authentication request, Silverfort acts before access is granted, not after the damage is done. That’s the only place attacks at this speed can still be stopped.

What is runtime Identity Security?

Runtime Identity Security means enforcing access controls inline, at the moment every authentication request happens, before access is granted. Rather than relying on static policies set in advance or reactive detection after the fact, runtime enforcement evaluates every access request dynamically, based on real-time risk signals, behavioral context, and policy, and acts immediately: allowing, blocking, stepping up, or restricting access.

Has Silverfort actually stopped Mythos-powered attacks?

Yes. In a controlled test at a large enterprise, Mythos achieved full domain compromise in roughly two hours. After Silverfort applied runtime Identity Security controls, the same attack paths were blocked inline. The security operations leader noted: “Silverfort is phenomenal. It blocked Mythos’ attempts to spread in the network. At some point we had to disable Silverfort’s defenses to allow further testing.” The full anonymous case study is available here.

How quickly can Silverfort be deployed?

Most organizations can be up and running within days. Silverfort integrates with your existing identity infrastructure—Active Directory, cloud IdPs, traditional PAM solutions. All without modifying servers, applications, or user workflows. There are no proxies to deploy, no architecture changes, and no user disruption.
