Vendor & Third-Party Risk
Know the risk your vendors bring with them
Third-party risk management — vendor tiering, due diligence, contract security terms, and continuous monitoring for the supply chain you actually have.
Vendor & Third-Party Risk services
What we deliver
Your security is increasingly other people's security — SaaS vendors, MSPs, processors, and their subprocessors. We build a third-party risk program that scales: tier vendors by real exposure, assess the ones that matter, and put teeth in the contracts.
Our areas of focus include:
Vendor Inventory & Tiering
A complete vendor map ranked by data access and business criticality — most orgs are surprised by their own list.
Due Diligence Workflows
Right-sized assessment per tier: SOC 2 review for critical vendors, attestations for the long tail.
Contract Security Terms
Breach notification SLAs, audit rights, data handling, and termination-data-return language that holds up.
Fourth-Party Visibility
Subprocessor tracking for the vendors behind your vendors.
Continuous Monitoring
Annual reassessment cadence plus event-driven reviews on breach news or ownership changes.
Offboarding Controls
Access revocation and data-return verification when a vendor relationship ends.
Testimonials
What clients say
“Principle Security was instrumental in guiding us through our recent infrastructure and cybersecurity initiatives. Their partnership was reliable, professional, and results‑driven, which is why we continue to engage them whenever new opportunities arise.”
“Their team helped us prioritize risk without overwhelming us with jargon or checklists. Practical guidance that actually moved the needle.”
“They stepped in during a critical project and brought stability fast—tight execution, clear communication, and zero babysitting required.”
“With their managed services handling patching, backups, and detection, our internal team finally has room to focus. Reliable, low-noise, and effective.”
“We didn't need a full-time CISO—we needed experience and flexibility. Their fractional leadership model gave us exactly that.”
“Our compliance program was scattered. They brought structure, clarity, and got us aligned with FFIEC and NIST—finally audit-ready and confident.”
“Principle Security helped us redesign our entire security stack without disrupting operations. They understood our infrastructure and delivered clean, scalable solutions.”
Drive your business forward.
We focus on execution, not theory — building security and infrastructure that actually supports your business.
