LSCP Challenging Cyber Resilience
Advisory · A year of security ownership · One budget

Your security person, long term.

I'm Sam Lyhin, founder of LSCP LLC. An advisory year works the way a good security hire works: one annual budget, paid monthly like a salary – and behind it, one person who owns your security questions all year. From "what do you make of this vendor?" to "I think my people are leaking to a competitor – take a look." The shape is the closest thing to a long-term security hire, without the headcount line.

Ask the first question

How the year works

The logic is deliberately simple: here is the year's budget – and here is all the work a security person is supposed to cover, with one line in your books and no surprise invoices.

What lands on the seat

Decisions

A call before a vendor is chosen, a technical check before a deal, a second opinion on the pentest report another firm delivered, a quiet read of "how bad is this?" – and yes, "look at what my own people are doing" belongs here too.

Architecture

Walkthroughs of what you're about to build – web, mobile, API, cloud, Active Directory, cryptography including post-quantum. Findings arrive as recommendations your team can implement.

The budget at work

Pre-allocation of budget means that the budget actually gets spent over the year – with more in-context Penetration Testing, and less surprising Incident Response.

What could be budgeted

Ask forAlready delivered
Web application pentestA decade of full-cycle testing, from scoping to exploitation and remediation validation; OSWE-backed white-box depth.
Mobile application pentest (iOS / Android)App and binary testing including reverse engineering, mapped to OWASP MASTG / MASVS; GMOB.
API pentestOWASP API Top 10, a standard part of full-cycle engagements.
Network, Active Directory & infrastructureLarge enterprise networks with BloodHound attack-path mapping and AV/IDS/IPS evasion; an engagement inside one of Europe's largest telecom providers.
Cloud pentest (AWS / Azure / GCP)All three major platforms, in client engagements.
Secure source-code reviewJava, Python, Go, Node.js, PHP, .NET, Erlang; two half-year review engagements on a national healthcare system, plus many smaller ones.
Enterprise PKI & cryptography assessmentA production post-quantum rollout delivered – ML-DSA (FIPS 204), design advisory plus post-implementation audit; two penetration-testing engagements for a central-bank-grade financial regulator; a B.S. in Applied Cryptology.
Red team / adversary emulationEmulation mapped to MITRE ATT&CK; built and ran a Big-4 offensive security practice – 10+ testers, ~200 engagements a year.
AI / ML red teamingApplication-layer testing mapped to MITRE ATLAS – prompt injection, model evasion – on production ML-powered platforms.
Real-time communications (WebRTC / VoIP)Original WebRTC Top-10 research, presented at OWASP Columbus – recorded.
IoT / hardware device testingHands-on device work; technical mentor at an IoT Village CTF.
Configuration reviewCIS Benchmarks up to DoD STIG level, under NIST 800-37.
Phishing & social engineeringCampaigns designed and run inside long-term client engagements.
Incident responseEnd-to-end casework: DarkGate malware, business email compromise, a production platform incident.
Exploit & vulnerability research12+ CVEs, published 0-day write-ups, the "MakeSense" Hack The Box machine, OffSec lab content – the Responsible Disclosure Lab.

Not a whole year yet?

You can still ask a question and I'll try my best to respond. But to give a deeply validated answer, I need to be in the context of your system. The annual budget is the best way to organize the understanding of this context.
