# A Cobalt alternative built for continuous, steerable testing

Cobalt delivers scheduled, human-run pentests through a marketplace of testers. Operator is a steerable, autonomous agent that runs continuously between engagements, returns exploit-proven findings, and offers a self-serve start with a free first scan so you can begin without a scoping call.

How They Differ

## Marketplace engagements versus a steerable agent

Cobalt is a Pentest-as-a-Service marketplace: you buy time-boxed engagements delivered by human testers. Operator is a continuous agent you can steer. The two answer different questions, and the difference shows up in cadence, pricing, and how findings arrive.

|  | Operator | Cobalt |
| --- | --- | --- |
| Delivery model | Steerable autonomous agent, human-on-the-loop | Marketplace of human pentesters |
| Cadence | Continuous re-testing | Time-boxed, scheduled engagements |
| Getting started | Self-serve, free first scan | 8-hour credit model, generally a scoping call to convert to scope |
| Pricing | Self-serve on-ramp, free first scan, plans scale by domain & depth | Engagement median ~$30k (third-party estimate) |
| Findings | Exploit-proven: request/response, repro, CVSS v3.1 | Human report per engagement |
| Compliance letter | Human validation on demand | Signed letter per engagement |

Cobalt has also launched Cobalt Autonomous, an AI pentest offering priced around ~$3,500 (third-party estimate). Operator differs in being steerable and human-on-the-loop with a self-serve on-ramp rather than a scoping-call credit model.

Where Cobalt Is Strong

## Deep, human-delivered engagements with a compliance letter

Cobalt built a mature marketplace of vetted human pentesters, and that is a real strength. When you need a scheduled, deep engagement with a named human team and a signed compliance letter at the end, a PTaaS marketplace is a proven way to get one.

For teams whose primary need is a point-in-time assessment on a fixed calendar, delivered by people, Cobalt is a credible choice. We do not position Operator as a replacement for that work. We position it as the continuous, steerable layer that runs alongside it.

- **Vetted human testers.** A marketplace of practitioners for scheduled, human-delivered engagements.
- **Compliance letters.** A signed letter per engagement for auditors and customers who require one.
- **Deep point-in-time work.** A strong fit when the need is periodic depth on a fixed calendar.
- **Established process.** A known scoping and delivery workflow many security teams already run.

Why Teams Pick Operator

## Continuous coverage between the deep engagements

The gap a scheduled pentest leaves is time. Your attack surface changes every deployment; an engagement every few months cannot see the exposure shipped last Tuesday. Operator closes that gap.

- **Continuous, not time-boxed.** Operator re-tests as your surface changes, so exposure from drift and routine deploys is caught that week, not at the next scheduled engagement.
- **Steerable and human-on-the-loop.** A named third category between fully-autonomous and human-validated. It runs on its own for breadth, and a human can steer it at business logic and edge cases when you want.
- **Self-serve on-ramp.** Start on the free first scan and move up through plans that scale by endpoint volume. No scoping call to convert credits into scope.
- **Exploit-proven findings.** Every finding ships with the request and response, reproduction steps, and CVSS v3.1 severity. Proof, not probability.
- **Recognized method.** Structured against OWASP WSTG, API Top 10, and ASVS, PTES, NIST SP 800-115, MITRE ATT&CK, and CVSS v3.1.
- **Human validation on demand.** Route any finding, or a full run, through a senior practitioner when you want a person's signature on the result.

FAQ

## Common questions

Is Operator a replacement for a Cobalt pentest engagement?

For continuous coverage, yes. Operator runs autonomously and continuously between the deep, scheduled engagements a human marketplace like Cobalt delivers. Many teams keep a periodic human pentest for a signed compliance letter and run Operator to hold the line every day in between.

How does pricing differ from Cobalt?

Operator offers a self-serve on-ramp with a free first scan, then paid plans that scale by endpoint volume. Cobalt's human PTaaS engagements have a median around $30,000 per engagement (third-party estimate) and generally begin with a scoping call to convert credits into scope.

Does Cobalt have an autonomous offering?

As of 2026 Cobalt has launched Cobalt Autonomous, an AI pentest offering priced around $3,500 (third-party estimate). Operator differs in being steerable and human-on-the-loop, with exploit-proven continuous findings and a self-serve on-ramp rather than a scoping-call credit model.

What does steerable mean here?

Operator sits between fully-autonomous and human-validated testing. It runs on its own for breadth, but a human can stay on the loop, directing it at specific business logic, edge cases, and priorities. You keep autonomy's constancy without giving up the ability to steer.

Do I still get evidence I can act on?

Yes. Every Operator finding is exploit-proven and ships with the request and response, reproduction steps, and a CVSS v3.1 severity. It is proof, not probability, so your engineers can confirm and fix without re-triage.
