Third Party Cyber Security Audit
A third party cyber security audit evaluates your vendors, partners, and external dependencies to uncover where trust introduces risk. The outcome is clear visibility into how external relationships expand your attack surface and where exposure must be addressed.
Let's Validate Your Security—For Real.
Prove What Actually Holds
If your defenses haven’t been tested under real attack conditions, they are unproven. We validate what actually holds—before it’s exploited.
- No generic assessments
- No junior resources
- No assumptions—only validated risk
Your Security Is Only As Strong As Your Weakest Vendor
The Real Exposure Lives Outside Your Organization
Understanding the Risk
Organizations depend on third parties for operations, technology, and services. Each connection introduces access, data exchange, and system dependency.
Without deep visibility, these relationships create hidden exposure. Attackers often target weaker vendors to gain entry. They bypass stronger internal defenses without confrontation.
What Third-Party Cyber Security Audit Covers
This service examines how external vendors connect into your environment, what access they hold, and how their controls align with your risk profile. It evaluates real exposure across integrations, data flows, and dependencies, highlighting where third-party risk creates direct pathways into your systems.
Key Capabilities
- Identify all third-party vendors, partners, and external integrations connected to your environment, and build a complete view of external dependencies along with their impact on security posture.
- Evaluate vendor access levels across systems and data, and expose excessive permissions or unnecessary privileges that increase risk through third-party accounts.
- Assess how data moves between your organization and external parties, including storage and transmission paths that may expose sensitive information.
- Analyze vendor security controls against internal standards, and reveal gaps that introduce risk into your environment.
- Map trust relationships across systems and integrations, and show potential paths attackers could use after compromising a vendor.
- Review contractual and compliance obligations tied to third-party security, and compare documented expectations against actual practices.
- Evaluate cloud-based vendors and service providers, and highlight configuration risks, shared responsibility gaps, and distributed exposure.
- Prioritize third-party risks based on exploitability and business impact, and focus attention on relationships that create the highest exposure.
- Deliver actionable recommendations to reduce vendor-related risk, and strengthen controls, access management, and oversight across external dependencies.

OT/ICS Security Testing
Overlooked Flaw
Insufficient segmentation between IT and OT networks enabling cross-environment compromise.
100+
Proven Experience
Completed 100+ OT/ICS engagements uncovering critical pathways into industrial systems.
Operational Technology environments support critical infrastructure across energy, oil & gas, utilities, manufacturing, and water systems—where security failures can have physical and safety consequences. Testing focuses on industrial control systems, SCADA networks, and the convergence between IT and OT environments.
Aligned with NERC CIP, NIST, and industry-specific standards, these assessments identify how cyber threats can impact operational continuity and safety. The goal is to uncover pathways attackers can use to move from IT into OT systems, disrupt operations, or manipulate critical processes.

FAQs
It is an assessment of vendors, partners, and external systems to identify how they introduce risk into your organization’s environment.
Attackers often target vendors with weaker defenses to gain indirect access, making third-party relationships a common entry point for breaches.
Regular audits are recommended, especially when onboarding new vendors, renewing contracts, or after changes in systems or integrations.
