What is Terra Security?
Terra Security runs continuous pentesting with swarms of AI agents and certified human pentesters in the loop. It tests web apps, external and internal networks (in public preview since May 2026) and AI systems, and sells through a demo.
Comparison at a glance
| Aspect | Barrion | Terra Security |
|---|---|---|
| What it tests | Web apps and APIs, including authenticated testing as several users in named roles. 8 testing areas and all 97 OWASP WSTG v4.2 cases | Web apps, external networks, internal networks (including Active Directory) and AI red teaming |
| How it validates findings | Every finding is checked against the live app. Confirmed ones come with the request and response that prove them. Anything unconfirmed is clearly marked and capped in severity | Findings verified for real exploitability and prioritised by business impact, then signed off by certified pentesters |
| Continuous and scheduling | On a schedule you set (daily to yearly, or a custom rhythm), every time or only when the app has changed, or on demand. Each run labels findings new, still open, resolved or regressed | Continuous pentesting. Specific triggers and schedule options not stated |
| Human involvement | AI agents do the testing. From Standard level up a security engineer reviews the findings, and deeper tests come with a report signed off by that engineer. Retests of found issues are free | Human pentesters on the loop. Intrusive actions need direct human approval, and certified pentesters sign off findings |
| Pricing model | Plans and per-run prices are public on the pricing page. Continuous programs are priced through sales | No public pricing |
| Self-serve or sales | Self-serve for single pentests. Continuous programs through sales | Through a demo |
| Data residency | Stored and hosted in Sweden. AI processing in the EU | Not stated on the pages we checked |
| What it doesn't do | No internal network, Active Directory, mobile, physical or social engineering testing | No public pricing or self-serve start. Mobile testing isn't mentioned |

Who Barrion is best for
Choose Barrion if your risk is in your web app and APIs, you want to start without a sales call, and you want public per-run prices. Human review of findings starts at Standard level, deeper tests come with a signed-off report, and data stays in Sweden with AI processing in the EU.
Who Terra Security is best for
Choose Terra if you need web apps and internal or external networks tested by one vendor, want certified pentesters approving intrusive actions and signing findings, or need audit-ready reports for SOC 2, ISO 27001 or HIPAA with human names on them.
Frequently asked questions
Is Barrion a Terra Security alternative?
For web apps and APIs, yes. Both run continuous AI pentests with human review. Terra also tests external and internal networks and AI systems, which Barrion doesn't, and its certified pentesters oversee the agents during testing.
Which one has more human involvement?
Terra. Its certified pentesters approve intrusive actions and sign off findings. At Barrion, AI agents do the testing, and from Standard level up a security engineer reviews the findings before the report is released. Deeper tests come with a report signed off by that engineer.
How do the prices compare?
Terra doesn't publish prices (checked 2026-09-26). Barrion's Essential plan starts at €199/month, per-run prices are on the pricing page, and scheduled pentests on the Business plan are priced through sales.
Does Terra test internal networks?
Yes. Terra launched internal and external network testing in public preview on 2026-05-20, including Active Directory attack paths. Barrion doesn't test internal networks or Active Directory.
Summary
Terra puts more human pentester time into each engagement and covers networks and Active Directory. Barrion is narrower, covering web apps and APIs, and quicker to start, with public prices and a security engineer reviewing findings from Standard level up. If your auditor wants network testing, Terra covers it and Barrion doesn't.
