Full-coverage offensive security — on a retainer, not a PO cycle.
One team. Seven practices. Delivered through a shared findings platform so you can prioritize, assign, and retest without leaving the tool you already use.
Findings platform
Your security program, without the PDF lag.
Every finding, PoC, retest, and auditor-facing artifact in one live view. Wired to Jira, Linear, GitHub, and Slack so the team that needs to fix it never leaves their tool.

Integrations that fit your workflow
One-way or two-way sync with Jira, Linear, GitHub Issues, Azure DevOps, Slack, Teams, PagerDuty.
Evidence your auditor accepts
Export SOC 2 / ISO 27001 / PCI-DSS-aligned artifacts with reproducible PoCs attached.
Live retest, not annual redo
Re-verification within 5 business days of fix — unlimited within the engagement window.
Where we plug in
Industry-shaped engagements, not a generic checklist.
We tailor scope, deliverables, and evidence artifacts to match your regulator, your buyer, and your release cadence.
Methodology
How we work — open, reproducible, auditable.
Every engagement maps to published frameworks (PTES, OWASP WSTG / MASVS, OSSTMM, NIST SP 800-115, MITRE ATT&CK) so your auditors and engineers see the same story.

In their words
Security leaders who switched to a continuous model.
Fifteen anonymized outcomes from payments, healthcare, SaaS, cloud, identity, and AI teams — edited only for confidentiality.
MTTR 11d → 3d
“PentStark's PTaaS retainer replaced three vendors for us. Findings land in Linear the same hour they're found, and the 'retest on fix' cadence finally matches how we ship.”
62% MTTD ↓
“Their red team didn't just run a scenario — they built us a purple-team backlog with atomic tests. We measured detection coverage for the first time and shipped four new SIEM rules the same week.”
8 exploit chains
“We had six months of LLM launches queued behind 'is this safe?'. PentStark's AI red team gave us a threat model, a CI eval suite, and an audit narrative we could actually ship.”
F500 deal · 45d
“We needed a report our Fortune 500 buyer would accept without another questionnaire loop. PentStark stood up the retainer in ten days, delivered the signed evidence, and stayed on every merge after the deal closed.”
14 AWS accounts
“We thought cross-account least privilege was solved. Their graph found one forgotten trust policy bridging non-prod into the production data plane, then they left us with policy-as-code that catches the same regression in every pull request.”
0 auditor follow-ups
“Five weeks before our SOC 2 window, they tested the merchant API, webhook service, and reconciliation jobs. The auditor accepted the evidence package with zero follow-ups, and none of the 14 findings regressed after remediation.”
12 gaps closed
“The purple-team workshop turned a successful PHI access path into twelve detection fixes we could verify. For the first time, our team could replay the same techniques instead of trusting a coverage dashboard.”
MTTR · 4.2d
“We stopped treating the pentest as a document handoff. Findings arrived with reproducible PoCs and layer-specific fixes, and our mean time to remediate reached 4.2 days with zero regressions on retest.”
100% CI reproducible
“They converted every LLM exploit path into a CI-ready evaluator. Our team can now catch prompt injection, tool abuse, and RAG poisoning before a release instead of after a customer report.”
7 MCP servers
“We had seven MCP servers in one agent runtime and no single owner of the combined trust boundary. PentStark chained injected tool output, path traversal, and shared credential access into a four-call exfiltration path — then gave us the inventory and isolation plan to close it.”
2 keys · 1 session
“Our passkey rollout looked phishing-resistant until they raced enrollment and registered a second key during the same session. We separated enrollment policy from login policy and added device attestation before expanding the rollout.”
5-part audit binder
“They turned the EU AI Act from a legal interpretation into an operating security program: threat model, versioned test plan, execution log, CI evals, and residual-risk sign-off. That five-part binder is what our first audit cycle needed.”
1 chained exploit
“Our public API authorization was correct, so we assumed tenant isolation was solved. PentStark pivoted through a webhook worker, reached internal services with SSRF, and returned cross-tenant data from a regular user account.”
72h objective window
“The board stopped asking whether backups existed and started asking how quickly an attacker could reach them. PentStark scoped a 72-hour assume-breach exercise with time-to-objective, a stage-by-stage detection matrix, and atomic tests our SOC can replay.”
40 findings · 0% regression
“Leadership, engineering, and compliance finally received the same report. Forty findings rolled into one executive risk narrative, a control-mapping matrix, and a retest delta; the regression rate stayed at zero after remediation.”
