Cogent vs Sentrint vs Vaultak (Where Agency Security Liability Actually Sits)
These three sit at different layers, so the real decision is which layer your retainer already promises to defend. Cogent covers infrastructure attack paths, Sentrint covers the code your delivery team ships, and Vaultak covers the agents you now run on a client's behalf; buying all three before you have a written scope for each is how agencies end up carrying liability they never priced. Pick the layer where a breach would end the client relationship, instrument it, and treat the other two as expansion line items once the first is documented in the contract.

Which should an agency choose?
Cogent vs Sentrint vs Vaultak (Where Agency Security Liability Actually Sits)
Cogent
Best for: Agencies holding security retainers with mid-market clients who want attack-path modeling plus a remediation paper trail.- VR-1 reasoning model maps attack paths across enterprise infrastructure rather than flagging isolated CVEs
- Covers vulnerability assessment, autonomous remediation, and client-ready reporting in one engagement
- The Cogent AI Harness gives defensive agents a contained runtime, which matters when a retainer promises monitoring
- Enterprise-network scope means small client estates get less value per dollar
- Autonomous remediation still needs a named human approver inside the agency
- No white-label path, so resale runs through your own brand and your own liability
Sentrint
Best for: Agencies shipping client web builds or internal tooling who need a repeatable pre-launch security gate.- Scans repositories for vulnerabilities, leaked credentials, and dependency risk in one pass
- Weighted security grade gives non-technical client stakeholders a number they can track quarter over quarter
- Each finding ships with an AI fix prompt that drops into whichever coding tool the delivery team already uses
- Repository-only view, so it says nothing about endpoint, identity, or network exposure
- Grades can be gamed by suppressing findings, which weakens them as contractual evidence
- Fix prompts still require a developer to review and merge
Vaultak
Best for: Agencies running multi-step agent workflows against client CRMs, inboxes, or ad accounts where an errant action is billable damage.- Sits between AI agents and the systems they touch, intercepting every action before it executes
- Scores actions across five risk dimensions and can block, pause, or roll back a violating action
- Deploys without code changes, so it can wrap automations already running for clients
- Governs agent behavior only, leaving conventional infrastructure exposure untouched
- Rollback coverage depends on whether the downstream system supports reversal
- Adds a policy-authoring step before any new client workflow goes live
