Kythos AI services
Authorized testing backed by disciplined engineering.
We assess security posture, test approved targets, validate findings, engineer fixes, and prove the result. Every engagement begins with ownership, scope, techniques, windows, exclusions, contacts, and stop conditions.
Authorized penetration testing
Test the attack path. Preserve the evidence. Fix what matters.
External and internal testing
Test named network, application, identity, endpoint, cloud, and infrastructure surfaces using techniques approved in the rules of engagement.
Vulnerability validation
Separate scanner output from reproducible conditions, establish practical impact, record uncertainty, and prioritize by exposure and business consequence.
Remediation engineering
Develop configuration changes, compensating controls, detections, software fixes, candidate patches, deployment plans, and rollback procedures.
Retest and handoff
Repeat the relevant test, document closure or remaining risk, and deliver evidence your operators can maintain.
AI-assisted defensive scope
Defensive AI capabilities for internal research and authorized workflows.
Vulnerability discovery and triage
Analyze code, artifacts, and evidence to surface likely weaknesses, remove noise, and organize human validation.
Code security review and threat modeling
Map trust boundaries, entry points, failure modes, and security properties before recommending changes.
Detection engineering and incident response
Develop and evaluate detection logic, investigate evidence, document hypotheses, and support containment and recovery planning.
Controlled malware analysis
Examine suspicious behavior and artifacts inside isolated, authorized environments with explicit handling controls.
Remediation and patch validation
Review proposed fixes, test whether they close the condition, check regression risk, and preserve acceptance evidence.
Offensive-security tasks require their own written scope, appropriate tooling, and explicit authorization. Access to a defensive model is never presented as blanket permission for penetration testing or red-team activity.
Urgent vulnerability response
A practical path from zero-day exposure to verified control.
Establish exposure
Inventory affected versions, reachability, privileges, dependencies, active indicators, and compensating controls.
Reproduce safely
Use an isolated lab and the minimum technique needed to validate impact without putting production at unnecessary risk.
Mitigate and patch
Apply vendor guidance where available or engineer a bounded temporary mitigation or candidate patch with rollback.
Validate and deploy
Confirm closure, test regressions, stage rollout, monitor results, and record remaining exposure.
Readiness and operations
NIST, MSSP, and evidence support.
Services include system-boundary review, NIST-aligned evidence preparation, requirement-level gap analysis, control implementation, remediation tracking, endpoint posture, identity review, scheduled vulnerability review, and retest support.
Formal certification decisions remain with authorized assessment bodies. Customer leadership retains risk acceptance and operational authority.
Written permission before testing
