Understand the Risk Behind Your External Dependencies

Symosis helps organizations assess suppliers, service providers, integrations, and acquisition targets.

We examine available evidence, technical access, data handling, and operational dependencies to support informed onboarding decisions, oversight, and remediation priorities.

01

Focus on the Relationships That Matter Most

Third parties can hold sensitive information, administer systems, connect to applications, or support critical business services. Their risk depends on those relationships and the safeguards around them.

Symosis helps you apply scrutiny proportionate to the access, information, and operational reliance involved.

Problems We Help Solve

  1. 01Vendor inventories lack clear owners or risk classifications.
  2. 02Security reviews apply the same questionnaire regardless of exposure.
  3. 03Assurance reports are collected without evaluating scope or exceptions.
  4. 04Vendor permissions and integrations exceed business requirements.
  5. 05Sensitive-data handling and subcontractor dependencies are unclear.
  6. 06Findings remain open without remediation commitments or risk decisions.
  7. 07Incident responsibilities and notification expectations are poorly defined.
  8. 08Acquisition decisions lack a practical view of security gaps and integration costs.

How Symosis Helps

01

Vendor Inventory & Risk Tiering

Identify which relationships require deeper review.

  • Define inventory requirements and accountable owners
  • Map services, data access, integrations, and business dependencies
  • Establish inherent-risk criteria and review tiers
  • Identify critical and higher-risk providers
  • Define reassessment and change-review triggers
  • Establish ownership for onboarding and ongoing oversight

You receive

Inventory requirements, risk-tiering criteria, and a prioritized review plan.

02

Third-Party Security Assessments

Evaluate the controls relevant to the relationship.

  • Review security documentation and questionnaire responses
  • Examine assurance reports, assessment scope, and exceptions
  • Evaluate identity, access, and administrative controls
  • Assess data protection and integration practices
  • Review incident management and recovery evidence
  • Clarify gaps through targeted questions and working sessions

You receive

Assessment findings, evidence gaps, and recommended risk-treatment actions.

03

Data, Access & Integration Risk

Understand how the provider connects to your environment.

  • Map sensitive information shared or processed
  • Review permissions, credentials, and delegated access
  • Assess APIs, connectors, and external-sharing arrangements
  • Examine retention and deletion practices
  • Identify relevant subcontractor dependencies
  • Recommend safeguards within your organization’s control

You receive

A relationship-level exposure assessment and prioritized control recommendations.

04

TPRM Program & Workflow Design

Make reviews repeatable and accountable.

  • Define intake and procurement checkpoints
  • Establish assessment requirements by risk tier
  • Develop escalation, exception, and risk-acceptance workflows
  • Assign finding owners and follow-up requirements
  • Define reporting and periodic review practices
  • Integrate the process with existing tools where appropriate

You receive

TPRM procedures, responsibility assignments, assessment templates, and reporting requirements.

05

Cybersecurity Due Diligence for Acquisitions

Identify security issues that could affect the transaction or integration.

  • Define review priorities around the target’s business and technology
  • Assess available security-program and technical evidence
  • Review identity, infrastructure, applications, and external dependencies
  • Examine known incidents, unresolved findings, and assurance gaps
  • Identify separation or integration concerns
  • Develop post-acquisition remediation priorities

You receive

A due-diligence summary, material findings, integration considerations, and a prioritized action plan.

03

Evidence Should Support the Decision

A completed questionnaire or assurance report provides useful information, but its relevance depends on scope, timing, exceptions, and the service you are buying.

Symosis identifies what the evidence supports, where uncertainty remains, and which additional safeguards or commitments should be considered.

Provider testing is included only when separately scoped and authorized.

04

From Findings to Risk Decisions

Our recommendations help your organization determine:

  1. 01Whether the relationship can proceed under existing safeguards
  2. 02Which issues require resolution before onboarding
  3. 03Which risks need accountable acceptance
  4. 04What remediation commitments should be tracked
  5. 05Which changes should trigger reassessment
  6. 06What questions require procurement, privacy, or legal review

Final business and risk-acceptance decisions remain with your organization.

Questions

What is tiering in TPRM?

Classifying vendors by data access and criticality so assessment depth matches risk.

Are questionnaires enough?

They are a start; higher-risk vendors warrant evidence review and contractual controls.

Can you run assessments ongoing?

Yes, through Managed Third-Party Risk.
