27-sec client review 🎥

Hear a client explain, in 27 seconds, why our manual-led web & API pentests deliver clearer findings, faster remediation, and compliance-ready evidence. Includes a free 30-day retest to validate fixes.

67-sec DFIR client review 🎥

Hear a client explain, in 67 seconds, how our evidence-first DFIR investigation helped them respond to a Windows malware incident and suspicious Apple ID access. We reviewed logs and network evidence (including a Wireshark capture) to build a clear timeline, validate suspicious activity, and deliver practical containment + recovery steps.

Engagement 01 Service: Web Application Penetration Testing Industry: SaaS – Software Development
Engagement 02 Service: API Penetration Testing (Windows Application) Industry: SaaS – Productivity Tools
Engagement 03 Service: API Penetration Testing (Call Center Platform) Industry: Communications Technology
Engagement 04 Service: Gray-Box Application Penetration Testing Industry: Technology – Software Platform
Engagement 05 Service: Internal Network Penetration Testing Industry: SMB – Retail / Professional Services

Testing identified internal network segmentation gaps alongside exposed management interfaces running default credentials on network devices. Findings were prioritized by exploitability. The client confirmed all hardening steps were completed within the engagement window.

Service: HIPAA Security Assessment Industry: Healthcare – Dental Practice Management Software

A HIPAA-aligned assessment of a patient data platform tested access controls, data transmission security, and audit logging completeness. Findings included insufficient encryption of data at rest and inadequate role-based access controls, both with direct implications under the HIPAA Security Rule. All issues were remediated with documented evidence suitable for compliance review.

Service: Security Assessment & Consultation Industry: MarTech – Digital Advertising

A review of internal tooling and cloud-hosted infrastructure surfaced misconfigured access policies and credential management gaps. Findings were prioritized by business risk, and the team received a remediation plan they could execute independently without additional consulting time.

Service: AI Application Security Review Industry: SaaS – Scheduling Platform

The review assessed an AI-powered scheduling application for prompt injection exposure, unauthorized data retrieval through model outputs, and insecure API integrations feeding user data into the model layer. Input validation gaps were identified that could allow user-controlled content to influence model behavior outside intended parameters. Controls were implemented before the public launch.

Service: Windows Endpoint DFIR Investigation Industry: Individual – Persistent Endpoint Compromise

The engagement involved a Windows system with a recurring compromise that multiple prior remediation attempts, including reimages, had failed to resolve. Forensic analysis identified a rootkit-level persistence mechanism and lateral credential access that survived reimaging. A full containment and recovery plan was delivered; the system was confirmed clean following implementation.

Service: DFIR Investigation – Malware & Unauthorized Account Access Industry: SMB

(Video review — 67 seconds)
Network log analysis and Wireshark capture review confirmed active malware on Windows endpoints alongside unauthorized Apple ID access from unrecognized geolocations. The investigation established a clear incident timeline, validated the scope of compromise, and produced containment and recovery steps actionable within the same business day.
