Announcement
Osto has been accepted into the Anthropic Cyber Verification Program. For a security company working across VAPT, red teaming, cloud security and detection engineering, verified access improves the research and reasoning layer behind authorized security work.
Better security reasoning inside authorized work
Osto’s work often requires exploitability analysis, adversary simulation and offensive-style reasoning in legitimate, scoped engagements. The Anthropic Cyber Verification Program helps reduce interruptions while prohibited uses remain blocked.
TL;DR
Osto has been accepted into the Anthropic Cyber Verification Program, a free, application-based program designed for legitimate cybersecurity work that can overlap with high-risk dual-use activity.
For Osto, this matters because our work often requires exploitability analysis, adversary simulation and offensive-style reasoning inside explicitly authorized engagements. Verified access reduces unnecessary interruptions while the same authorization and human-review boundaries remain in place.

Security work has an unusual problem. The same reasoning that helps a defender understand an attack path can look offensive to a general-purpose AI safeguard. A penetration tester and an intruder can ask technically similar questions, even though only one is operating under authorization.
What the Anthropic Cyber Verification Program is
The Anthropic Cyber Verification Program, or CVP, is Anthropic’s route for verified cybersecurity professionals whose legitimate work can otherwise be affected by safeguards around high-risk dual-use cyber activity.
The important distinction is that verification does not make every cyber request permissible. It gives approved defenders more room to perform legitimate work while prohibited activities remain prohibited.
How the boundary works
Secure code review, hardening guidance, policy work and lower-risk defensive analysis.
Exploitability research, adversary simulation and certain offensive security tooling in legitimate contexts.
Activities such as mass data exfiltration or ransomware development remain blocked.
Why Anthropic Cyber Verification Program acceptance matters
For us, the significance is operational. Security work becomes less useful when analysis ends at “a vulnerability exists.” Clients need to understand whether the weakness is reachable, what an attacker could chain it with, which asset becomes exposed and what should be fixed first.
That is the gap between a finding and a real risk.
From finding to decision
What deeper reasoning improves
The Anthropic Cyber Verification Program helps approved defensive organizations use advanced model reasoning with fewer interruptions when that work legitimately crosses into dual-use territory.
Why this matters specifically for Osto
Osto works across web and API VAPT, cloud infrastructure assessment, red team exercises, source code review and detection engineering. A meaningful part of that work requires thinking about what an attacker would actually do with a weakness.
Consider an assessment that returns 80 findings. A severity score can help sort them, but it cannot tell a client whether an issue is actually exposed, protected by compensating controls, reachable from the internet or useful as part of a larger attack path.
That is why verified access matters most after a vulnerability has already been discovered. It strengthens the reasoning layer that turns a list of findings into a remediation plan.
| Without deeper attack-path reasoning | With scoped adversarial analysis |
|---|---|
| Severity-led triage | Reachability and real-world impact considered alongside severity |
| Detection based mainly on static indicators | Detection logic informed by modeled attacker behavior |
| Individual findings treated separately | Weaknesses evaluated as possible attack chains |
Where this shows up in our work
Exploitability analysis
Separating findings that are realistically reachable from findings that exist mainly on paper.
Detection engineering
Reasoning about attacker behavior across signals instead of depending only on static signatures.
Threat modeling
Pressure-testing assumptions, trust boundaries and control gaps before an attacker discovers them.
Red team research
Studying realistic attacker paths inside a clearly agreed and explicitly authorized scope.
VAPT prioritization
Turning dozens of findings into a clearer view of which issues need action first and why.
Across every engagement, the difficult part is rarely producing a longer report. It is establishing a defensible line between a technical finding and a business-relevant security risk.
The other direction: AI is changing the attacker too
AI is not only improving defensive workflows. Attackers have access to increasingly capable automation and reasoning tools as well. Any security program that models only yesterday’s attacker will eventually fall behind.
Verified access helps legitimate researchers study offensive capability within a controlled process so defenses can reflect what is possible now, not what was common several years ago.
The goal is not offensive capability for its own sake. The goal is better defense.
What it means for clients
Clients should not expect the dashboard to look different tomorrow. The improvement happens upstream, in the research and analysis feeding VAPT reports, code-security findings, cloud assessments and cross-module detection.
- ✓Sharper triage. Fewer findings that lead nowhere and a clearer line between critical exposure and noise.
- ✓Better attack-path context. Guidance considers what an attacker could realistically chain together, not only the isolated score of each issue.
- ✓More useful remediation. Recommendations are shaped by likely impact and control context rather than generic checklist language.
- ✓Research that keeps pace. Defensive analysis can better reflect the way AI-assisted attack capability is evolving.
- ✓The same authorization boundaries. Verified access changes the quality of analysis, not what Osto is permitted to touch.
The authorization boundary does not change
Every client engagement continues to operate within its agreed scope and written authorization. Systems outside that scope remain outside it. Human security professionals continue to review analysis before it reaches a client.
AI supports the research and reasoning layer. It does not replace professional judgment, client authorization or engagement controls.
Acceptance into the Anthropic Cyber Verification Program strengthens that research layer without changing those fundamentals.

Book a DemoFrequently asked questions
Does verification lift every cyber restriction?
No. CVP is intended to reduce interruptions for legitimate dual-use cybersecurity work. Prohibited cyber activity remains restricted regardless of verification status.
Does this mean AI now runs Osto’s penetration tests?
No. Osto’s penetration testing remains expert-led. AI can improve research, exploitability reasoning, threat modeling and prioritization, while human security professionals remain responsible for the engagement and client-facing output.
Does verification change what Osto can test?
No. Testing remains limited to systems Osto owns or is explicitly authorized to assess under the agreed engagement scope.
Who can apply to the Anthropic Cyber Verification Program?
Anthropic describes CVP as a free, application-based program for cybersecurity professionals with legitimate use cases that can be affected by cyber safeguards.
Does the Anthropic Cyber Verification Program remove safeguards completely?
No. The program provides greater room for approved dual-use defensive work. It does not remove restrictions around prohibited cyber activity.
