Independent Software Vendors (ISV)

SaaS, on-prem vendors, critical middleware

Your code circulates among your customers. Not all of them are friends.

Supply-chain attacks, competitor reverse engineering, unaudited open-source dependencies. SolarWinds 2020: 18,000 organizations hit via a legitimate, signed update. The CRA now imposes continuous responsibility across the entire software lifecycle.

AN EDITOR IS ALWAYS A POTENTIAL DISTRIBUTION VECTOR

SolarWinds, 3CX, XZ Utils: your update as a weapon
Supply-chain attacks compromise the vendor to infect all its customers simultaneously. SolarWinds 2020: 18,000 organizations via a signed update. XZ Utils 2024: a backdoor in an open-source dependency embedded in millions of Linux systems.
Your algorithms in your competitors' hands
Delivered binaries can be disassembled in a few hours. Proprietary protocols, hard-coded keys, business logic — everything is readable. Your competitors do it. States do it. Binary analysis is the first step of software industrial espionage.
Log4Shell ×1000: the libraries hidden in your products
Your product integrates dozens of open-source libraries. Each is a potential CVE for which you are now responsible. Without a complete SBOM, you can't answer your customer's question: are you exposed?
Responsibility across the entire commercial lifecycle
The CRA mandates an SBOM, vulnerability reporting within 24h, and demonstrable security by design throughout the commercial lifespan. Critical-middleware vendors are on the front line.

OUR SERVICES

QREDTEAM

ADVERSARY SIMULATION

  • Supply-chain Red Team — end-to-end SolarWinds-like attack simulation
  • Testing of distribution and update mechanisms — signing, channels, verification
  • Pentest of APIs and admin interfaces exposed to customers
  • Compromise simulation via third-party connectors and integrations (OAuth, webhooks)
  • Red Team of the build infrastructure — tampering detection in artifacts.

QLAB

DEEP SECURITY RESEARCH

  • Complete SBOM audit of deliverables — hidden components, licenses, CVEs (CRA/DORA/FDA)
  • Reverse engineering of delivered binaries — debug backdoors, hard-coded keys
  • 0-day research in your product’s critical components
  • CI/CD pipeline security audit — tampering detection in artifacts
  • Open-source dependency analysis and CVE mapping for regulatory compliance.

QSHIELD

SOFTWARE PROTECTION

  • Protection of binaries against reverse engineering and competitor decompilation
  • Anti-cloning for vendors exporting to risky markets (Asia, Middle East)
  • Obfuscation of proprietary algorithms and embedded business logic
  • Anti-tamper for deliverables — integrity guarantee between your build and the end customer
  • IP protection of rule engines and AI algorithms embedded in your products.

QUARKSLAB DIFFERENTIATOR

Vendors have their source code audited — rarely the binaries actually delivered. Quarkslab audits what runs at your customers’ sites: the signed compiled binary, not the code shown to the auditor. We identify hidden third-party components, embedded keys, persistent debug backdoors — and QShield makes your deliverables resistant to competitor or nation-state reverse engineering.

WHAT WOULD WE SAY TO EACH OTHER, FACE TO FACE

Do you know what an engineer can extract from your delivered binary in a single working day?

Most vendors run source-code reviews and vulnerability scans on their codebase. Very few have audited what is actually delivered to their customers — the compiled, signed, distributed binary. Yet that’s where your IP is exposed and where debug backdoors persist in production.

Documented, defensible compliance
We produce a complete SBOM of your deliverables, identify undeclared components, and give you an actionable CRA roadmap — not a PDF report.
Can your CI/CD be weaponized?
A supply-chain attacker targets your build pipeline, not your code. We simulate an end-to-end compromise — from commit to delivered binary.
Your code stays yours
QShield makes your binaries resistant to reverse engineering. What you deliver remains your exclusive property.
No tool to sell
Quarkslab doesn't sell SAST or DAST. Our only interest is finding what your automated tools missed.
