Penetration Testing That Actually Matters
Go beyond checkbox compliance. Our expert-led penetration tests simulate real-world attacks to find vulnerabilities that automated scanners miss.
The cybersecurity challenges you're facing
Whether you're a CISO building a security program, an IT leader managing risk, or an executive answering to the board - we've helped organizations like yours.
Compliance requirements are mounting
SOC 2, ISO 27001, PCI-DSS, HIPAA. Regulators and customers demand proof of your security posture.
You’re unaware of your blind spots
Hidden vulnerabilities in your systems could be exploited tomorrow. Uncertainty is your biggest risk.
Internal teams are stretched thin
Your security team is busy keeping lights on. Deep-dive testing requires specialized expertise.
Board and stakeholders want assurance
Leadership needs confidence that critical assets are protected. "We think we're secure" isn't enough.
Previous tests didn't deliver value
PDF reports that gathered dust, generic findings, no clear path to improvement.
Third-party risk is increasing
Your vendors, APIs, and integrations expand your attack surface. Supply chain attacks are rising.

iOS and Android security assessment including app internals, data storage, and backend APIs.
API & Microservices
Focused testing of REST, GraphQL, gRPC, and microservices architectures.
SaaS Application Testing
Multi-tenant security assessment for SaaS platforms and cloud-native applications.
These categories represent just a fraction of our testing capabilities. Each engagement includes thousands of individual security checks, both manual and automated. Discuss your specific requirements →
Go beyond penetration testing with Red Team Operations
While penetration testing finds technical vulnerabilities, Red Team operations test your entire security program: people, processes, and technology working together under realistic attack conditions.
- Multi-Vector Attacks: phishing, physical access, and technical exploitation
- Objective-Based Testing: achieve specific goals like accessing CEO email
- Detection & Response Validation: test if your SOC catches attacks
- Executive War Games: tabletop exercises for leadership decision-making
Aligned with your business objectives
Different approaches surface different risks and opportunities. We guide you toward the ones that matter most.
Black Box
We simulate a real external attacker with zero prior knowledge. Just like a threat actor would approach your organization.
- Realistic attack simulation, compliance requirements, external threat assessment
Grey Box
Testing with partial access, like a compromised employee, malicious insider, or partner with limited credentials.
- Insider threat assessment, post-authentication security, privilege escalation testing
White Box
Complete access to architecture, source code, and documentation. Maximum depth and coverage.
- Thorough security review, pre-release testing, maximum vulnerability discovery
Red Team Testing
Full-scope adversary simulation designed to test detection, response, and overall organizational resilience.
- Includes social engineering, privilege escalation, lateral movement, and real-world attack scenarios.
How a penetration test unfolds (standard flow)
Structured, collaborative, and transparent - delivering clear insights and prioritized actions that reduce risk fast.
Discovery & Scoping
We understand your environment, business context, and objectives. Together, we define the scope, rules of engagement, and success criteria.
Reconnaissance & Analysis
Our team gathers intelligence about your target environment: mapping the attack surface, identifying technologies, and planning attack vectors.
Active testing
Hands-on security testing by certified professionals. We identify vulnerabilities, chain findings, and document everything in real-time.
Analysis & Reporting
Findings are analyzed, validated, and translated into actionable recommendations with clear prioritization.
Delivery & Debrief
We present findings to both technical and executive stakeholders, ensuring everyone understands the risks and next steps.
Remediation support & retest
We're here to help. Ask questions about findings, get guidance on fixes, and verify remediation with free retesting.

Frequently asked questions
Most engagements take 2-4 weeks from kickoff to final report. The active testing phase typically runs 5-10 business days depending on scope. We can accommodate urgent timelines when needed.
We design our testing to minimize disruption. Dangerous tests (like DoS) are only performed with explicit approval and during maintenance windows. We maintain constant communication and can pause immediately if issues arise.
Our team holds OSCP, OSCE, OSWE, OSEP, CRTO, CREST, and other industry-recognized certifications. Many team members are also active CTF competitors and CVE researchers.
Yes! Every engagement includes free retesting to verify your remediations are effective. We want you to be confident that vulnerabilities are truly resolved.
Absolutely. We provide attestation letters and reports formatted for SOC 2, ISO 27001, PCI-DSS, HIPAA, and other frameworks, such as NIS2, GDPR and local regulations (e.g. ASF, BNR). We can scope engagements specifically for compliance needs.
Three things: 1) Our team's CTF and bug bounty background means we think like real attackers. 2) Real-time portal access keeps you informed throughout. 3) We focus on actionable findings, not padding reports with scanner output.
