Security reviews, SOC 2, or ISO 27001 slowing down your deals? I step in as your Virtual CISO, take ownership of your security, align it with business goals, and get you enterprise ready. I work with SaaS and AI companies to remove compliance bottlenecks, accelerate deal cycles by 20-40%, and build security programs that support growth and enterprise sales. $𝟮𝟬𝗠+ 𝗥𝗘𝗩𝗘𝗡𝗨𝗘 𝗘𝗡𝗔𝗕𝗟𝗘𝗗 | 𝟱𝟬+ 𝗖𝗟𝗜𝗘𝗡𝗧𝗦 | 𝗘𝗡𝗗-𝗧𝗢-𝗘𝗡𝗗 𝗘𝗫𝗘𝗖𝗨𝗧𝗜𝗢𝗡 𝗧𝗛𝗘 𝗣𝗥𝗢𝗕𝗟𝗘𝗠 Enterprise deals slow down when security becomes a blocker. A large customer asks for a security review. Then another. Questionnaires pile up, documentation is incomplete, and your team is pulled into processes they are not prepared for. Timelines slip, audits feel unclear, and compliance starts consuming time that should be spent scaling the business. This is where most SaaS, fintech, healthtech, and AI companies hit a wall. 𝗛𝗢𝗪 𝗜 𝗢𝗣𝗘𝗥𝗔𝗧𝗘 I operate as a Virtual CISO, taking ownership of your security and compliance function and turning it into a structured system that supports how your company sells, operates, and grows. Not as an external consultant delivering recommendations but as an embedded operator responsible for execution, structure, and outcomes. 𝗠𝗘𝗔𝗦𝗨𝗥𝗔𝗕𝗟𝗘 𝗥𝗘𝗦𝗨𝗟𝗧𝗦 Companies working this way see measurable improvements. • 𝟮𝟬-𝟰𝟬% 𝗳𝗮𝘀𝘁𝗲𝗿: Enterprise sales cycles are reduced as security reviews stop delaying deals. • 𝟯𝟬-𝟱𝟬% 𝘀𝗵𝗼𝗿𝘁𝗲𝗿: Audit preparation timelines are shortened by 30-50% through structured controls and documentation. • 𝟱𝟬%+ 𝗿𝗲𝗱𝘂𝗰𝘁𝗶𝗼𝗻: Time spent on security questionnaires drops significantly, by more than half. • 𝗙𝗮𝘀𝘁𝗲𝗿 𝘁𝗿𝘂𝘀𝘁: Deal velocity increases as enterprise clients gain faster trust in your security posture. 𝗠𝗬 𝗔𝗣𝗣𝗥𝗢𝗔𝗖𝗛 My approach is execution-first. I work directly with your team to design controls, build documentation, structure your compliance program, and align everything with business objectives. This includes: • SOC 2 readiness and audit execution • ISO 27001 implementation and ISMS structuring • Security documentation and control frameworks • Vendor security questionnaires and enterprise reviews • Risk management, governance, and GRC programs I also support modern environments, including AI systems and cloud infrastructure (AWS, Azure, GCP), ensuring they align with compliance frameworks and enterprise expectations. 𝗪𝗛𝗬 𝗧𝗛𝗜𝗦 𝗠𝗔𝗧𝗧𝗘𝗥𝗦 If you sell to enterprise clients, security and compliance are not optional they are required to unlock revenue. 𝗧𝗛𝗜𝗦 𝗜𝗦 𝗔 𝗦𝗧𝗥𝗢𝗡𝗚 𝗙𝗜𝗧 𝗜𝗙 𝗬𝗢𝗨 𝗔𝗥𝗘 • Preparing for SOC 2 or ISO 27001 and need a clear execution path • Losing or delaying deals due to security requirements • Managing security questionnaires manually and inefficiently • Using tools like Vanta, Drata, Thoropass, Secureframe, or similar but lacking structure • Scaling a SaaS, AI, fintech, or cloud business • Looking for ongoing Virtual CISO support 𝗪𝗵𝗮𝘁 𝗖𝗵𝗮𝗻𝗴𝗲𝘀 𝗪𝗵𝗲𝗻 𝗪𝗼𝗿𝗸𝗶𝗻𝗴 𝗧𝗵𝗶𝘀 𝗪𝗮𝘆 Working this way changes how your business operates. • Security stops being a blocker in sales cycles. • Audit processes become predictable and efficient, with minimal exceptions. • Internal teams regain time previously lost to compliance overhead. • Enterprise readiness improves, enabling access to higher-value accounts. • Risk becomes visible, structured, and actively managed. 𝗠𝗬 𝗧𝗥𝗔𝗖𝗞 𝗥𝗘𝗖𝗢𝗥𝗗 ✓ Enabled clients to unlock and protect over $20M+ in enterprise revenue ✓ Saved clients $50K-$250K by optimizing security tools and compliance strategies ✓ Reduced audit preparation time by 30-50% through structured execution ✓ Cut security questionnaire workload by 50%+, accelerating enterprise deal cycles ✓ Supported 50+ clients across SaaS, fintech, healthtech, and regulated industries ✓ Built SOC 2 and ISO 27001 programs aligned with real business operations ✓ Supported global teams across multiple time zones in long-term engagements ✓ Hands-on experience across governance, risk, compliance, and security programs 𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝗮𝗻𝗱 𝗖𝗼𝗺𝗽𝗹𝗶𝗮𝗻𝗰𝗲 𝗙𝗿𝗮𝗺𝗲𝘄𝗼𝗿𝗸𝘀 SOC 2 | ISO 27001 | ISO 27017 | ISO 27018 | ISO 42001 | NIST 800-53 | NIST 800-171 | NIST CSF | NIST AI RMF | FedRAMP | CMMC | CMMI | PCI-DSS | HIPAA | HITRUST CSF | GDPR | TISAX | NERC | FFIEC | C5 | ENISA | CIS CSAT | IRAP | PIPEDA | TX-RAMP | StateRAMP | AZ-RAMP | NY DFS 23 NYCRR Part 500 | EU AI Act 𝗜𝗳 𝘀𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝗶𝘀 𝗯𝗹𝗼𝗰𝗸𝗶𝗻𝗴 𝗴𝗿𝗼𝘄𝘁𝗵, 𝗺𝗲𝘀𝘀𝗮𝗴𝗲 𝗺𝗲.

Penetration tester and cybersecurity specialist offering VAPT for web applications, APIs, and network infrastructure. I find the exploitable weaknesses in your systems before a real attacker does, prove each one with a working proof of concept, and rate it by the actual risk to your business. I've worked both sides of security. I test systems the way an intruder would — real ethical hacking, not a checklist — and as a SOC analyst I've watched those same attacks surface in the logs. So I don't just hand you a list of problems. I can tell you what a real breach would look like on your side and how to catch the next one early. Most "penetration test" reports are a scanner's output dumped into a PDF and padded with false positives. I don't work that way. Every finding is tested by hand, proven with a working PoC, and written so your developers fix what counts instead of chasing noise. What I do: - Web application penetration testing — full OWASP Top 10 coverage - API security testing for REST and GraphQL - Internal and external network and infrastructure VAPT - Vulnerability assessment with clear remediation guidance - Cloud and SaaS security assessments - SOC support: SIEM monitoring, log analysis, threat detection, incident response - Reviewing existing scan results and stripping out the false positives What I regularly find: SQL injection, SSTI, command injection, XSS, CSRF, IDOR and broken access control, authentication and session flaws, business logic abuse, API weaknesses, and server and cloud misconfigurations. Every report gives you a severity rating, the business impact in plain English, steps to reproduce, and remediation your developers can ship right away. All work is fully authorized, kept inside the agreed scope, and confidential. Send me your scope, or just tell me what's keeping you up at night, and I'll walk you through how I'd test it and exactly what you'll get back.
