Cybersecurity

How do we make autonomous cyber defense dependable?

AI defenders need to stop attacks without harming the systems they protect. Fide studies the evidence, controls and oversight that could make this possible, moving from investigations of public records to controlled comparisons of defensive methods.

From evidence to defense

Better defense starts with a better account of what happened.

Our investigations examine what incident records establish, what reports leave unresolved and where controls stop short. We use those findings to develop testable questions about autonomous response.

Analysis

DSEWiki →

We checked claims in AI-written incident reports against the underlying records. Better overall scores could coexist with surviving errors.

The question for defense

Can a defender rely on the report it receives?

Visual investigation

URLQuery →

We reconstructed a known sequence across services, separating submitted instructions, recorded requests and recorded output. Transluce discovered the activity.

The question for defense

What downstream actions should a permission check cover?

These questions inform our planned autonomous-response study. The investigations do not establish how well an AI defender would perform.

Public research tool · Preview

Follow the field as it moves.

The Agentic Cyber Explorer is a sourced, regularly updated record of AI agents in cybersecurity.

It chronicles attacks carried out with AI agents and attacks on them, capability evaluations, defenses, and policy. Each claim links to its sources and carries a status that changes as new work arrives. Key questions summarize where the evidence stands, and research openings mark where it runs out, including questions tied to this program.

Public research tool

Practice the judgment behind dependable defense.

An AI defender may take the right-looking action while leaving the outcome uncertain.

The Defense Evidence Lab uses public records and published evaluation methods to help readers ask what happened, what changed, and what still needs to be verified before trusting a response or report. Where the explorer is the record, the Lab is the practice.

Current studies

From observing failures to testing better defenses.

Investigations surface questions worth testing. Our studies turn those questions into comparisons, with methods and findings added to each project’s record as the work develops.

Flagship study · Planned

When the Defender Becomes the Threat

When should an AI cyber defender act, wait, or hand control back to a human?

A proposed study of when additional oversight reduces harmful intervention without making autonomous defense ineffective. We will compare permission checks with escalation and approval under uncertain evidence.

Where it stands

Study direction selected. Collaborator, environment and final protocol remain to be qualified; experiments have not begun.

Next milestone

Qualify one defensive task and simulation with a cybersecurity collaborator, then run a feasibility pilot before fixing the main comparison.

What the study would measure

  • Service disruption at comparable attack containment
  • Attempted and executed authority violations
  • Unnecessary intervention and response delay
  • Supervision effort and evaluation cost

When Security Evaluations Go Stale

Fide is developing a study of whether targeted retesting catches meaningful performance declines, or gives false reassurance. We begin with AI malware-report analysis, comparing smaller retests against complete benchmark reruns.

Research directions

Start with the decision to act. Build from there.

Controlled response is our first focus. Verification of repair and recovery is the next direction; resilience across teams of defenders is a longer-term question. Each step needs suitable cases, collaborators and resources before experiments can begin.

  1. 01 · First focus

    Controlled autonomous response

    Can an AI defender stop an attack without disrupting the systems it is meant to protect?

    Begin with the decision to intervene. Our planned study compares permission checks with additional oversight, measuring containment alongside service disruption.

  2. 02 · Next direction

    Verified repair and recovery

    How do we know an AI-generated fix actually restores security?

    Extend the question from stopping an attack to establishing that a repair worked. A first study needs a reproducible repair case and a software-security collaborator.

  3. 03 · Longer-term direction

    Resilient AI defense teams

    Can a team of AI defenders keep protecting a network when one agent is compromised?

    Study how failures spread across cooperating defenders once we have suitable tasks and evidence checks. This depends on additional methods, resources and multi-agent expertise.
