Respond to product vulnerabilities with speed and trust.
Establish a mature product security incident response capability that protects customers, coordinates engineering, and preserves confidence.
What is Product Security Incident Response?
Establish a mature product security incident response capability that protects customers, coordinates engineering, and preserves confidence.
Hackstack Security delivers it as a scoped, agentic engagement: AI agents on local and client-approved API models expand coverage, our specialists test the logic and attack chains agents miss, and every finding is validated by a human, explained in business terms, and retested after you fix it.
- AI agents plus manual testers
- Human-validated findings only
- Retest and closure status included
What outcomes should you expect?
Every engagement is designed around the risk your team needs to understand and the action it needs to take.
Faster vulnerability response
Disclosure readiness
Reduced customer impact
What does PSIRT testing cover?
Proven methodology plus the judgment needed to uncover context-specific risk.
PSIRT program design
Vulnerability intake and triage
Coordinated disclosure management
Security advisory development
CVSS scoring and prioritization
Tabletop exercises
When should you run PSIRT testing?
Test before a finding turns into a release delay, a customer escalation, or an incident.
Before a major launch, migration, or architecture change
When enterprise customers or partners request security evidence
After meaningful changes to identity, data, integrations, or infrastructure
When your team needs an independent view of real-world risk
Which questions do we test?
Frameworks support consistent coverage. The assessment remains driven by your architecture, trust boundaries, threat model, and business workflows.
- Are incident roles, authority, and escalation paths understood?
- Can responders obtain the evidence needed to scope and contain an incident?
- Can business, legal, communications, and technical teams coordinate decisions?
- Are recovery actions prioritized and verified before normal operations resume?
- Reproducible request, response, configuration, or workflow evidence
- Attack-path narrative connecting technical behavior to business impact
- Control-focused remediation guidance and verification criteria
How does Hackstack Security test?
Testing is scoped, evidence-led, and designed to reduce risk without creating unnecessary disruption.
Context first
We learn the system, users, trust boundaries, and business objectives before testing begins.
Expert-led testing
Automation supports coverage. Human analysis finds the issues that depend on judgment and context.
Clear prioritization
Findings are ranked by exploitability, impact, and what matters to your organization.
Remediation partnership
We stay engaged through fixes, answer engineering questions, and validate closure.
What will you receive?
Reports are written for the people who need to make decisions, fix issues, and demonstrate improvement.
Executive summary and risk narrative
Detailed technical findings
Risk rating and prioritization
Exploit evidence and reproduction steps
Developer-friendly remediation guidance
Retest status and closure validation
PSIRT questions, answered.

What does Product Security Incident Response include?
It covers PSIRT program design, vulnerability intake and triage, coordinated disclosure management, security advisory development, CVSS scoring and prioritization, and tabletop exercises. Each engagement is scoped to your environment and ends with validated findings, remediation guidance, and a readout.
What will we receive at the end?
You receive an executive summary, detailed technical findings with exploit evidence and reproduction steps, risk ratings, developer-ready remediation guidance, and retest status. The goal is faster vulnerability response, disclosure readiness, reduced customer impact.
Which frameworks guide the testing?
Coverage is aligned with NIST SP 800-61r3 Incident Response Recommendations, NIST Cybersecurity Framework 2.0, CISA Cybersecurity Incident & Vulnerability Response Playbooks, then shaped by your architecture, trust boundaries, and business workflows.
Do you use AI agents or only manual testing?
Both. AI agents running on self-hosted local models, and on API-based models when you approve them, handle reconnaissance, surface mapping, fuzzing, and hypothesis generation, while our specialists test business logic and chained attacks manually. Every result is validated by a practitioner before it is reported.
Can you support remediation and retesting?
Yes. We walk your engineers through findings, answer implementation questions, and retest agreed fixes to document final status for stakeholders and auditors.
