Security Assessments
Know which vendors increase risk, and what to do about it.
Third-party tools and service providers are part of how you operate, but they also expand your attack surface. Nexeris helps you assess vendor security controls, understand risk, and put practical requirements in place without turning procurement into a bottleneck.

Strategic Value
Why Vendor Security Matters
Most organizations rely on dozens of vendors. Some handle sensitive data, have privileged access, or sit in the middle of critical workflows.
The goal isn’t to eliminate vendors. It’s to understand risk before you commit, avoid surprises after onboarding, and make sure you have the right safeguards in place. A good vendor assessment helps you ask better questions, evaluate evidence, and make consistent decisions.
Common reasons teams engage us:
- Procurement needs a consistent process for security reviews
- Leadership wants more visibility into third-party risk
- Customer, partner, or audit expectations require vendor oversight
- You’ve had vendor-related incidents, near misses, or unacceptable surprises
Your Vendor Security Assessment Engagement Includes
You’ll get a repeatable approach to vendor reviews, plus actionable findings you can use in onboarding, renewals, and risk decisions.
Vendor Intake and Scoping
- Determine which vendors require review based on data, access, and business criticality
- Define review tiers so low-risk vendors don’t get over-scrutinized
- Establish what “minimum security expectations” look like for your organization
Security Review and Evidence Evaluation
- Vendor questionnaire review with follow-up questions that cut through marketing claims
- Evidence review (policies, reports, attestations, architecture summaries) when available
- Evaluation of key control areas: access control, data handling, logging, incident response, and change management
Risk Scoring and Recommendations
- Practical risk scoring tied to impact and exposure
- Recommended remediation actions or compensating controls
- Decision guidance: approve, approve with conditions, or reject
Contract and Ongoing Oversight Guidance
- Security requirement recommendations you can include in contracts
- Renewal and re-assessment cadence suggestions
- A simple documentation approach so vendor reviews stay consistent over time

Common Questions
Is this the same as vendor management?
Vendor security assessments are focused on security risk and controls. Vendor management can include broader performance, pricing, and operational oversight.
Do we need to assess every vendor?
No. A tiered approach is best. We focus on vendors with sensitive data, privileged access, or business-critical dependency.
What if a vendor won’t share documentation?
We document what was requested, what was provided, and what remains unknown. Then we recommend decision options and compensating controls.
Can you help with contract language?
Yes. We can recommend security requirements and clauses based on the risk and vendor type.
How often should vendors be re-assessed?
It depends on the risk tier. High-risk vendors typically need more frequent review, especially around renewals or material changes.
