Comparison at a glance
| Aspect | Barrion | Pentera |
|---|---|---|
| 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 | Internal networks, the external attack surface (including internet-facing web apps), Active Directory, and cloud identity and hybrid environments |
| 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 | Runs real attack techniques safely, with controlled execution and audit proof |
| 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 | Anytime, on demand, across the internal and external attack surface |
| 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 | Your team runs the platform. No vendor pentester review stated |
| 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 | Its site centres on network, AD and cloud identity. Authenticated, multi-role testing of web app logic isn't described |

Who Barrion is best for
Choose Barrion if your main risk is your own product: the web app and APIs your customers log into. It tests them as several users, finds access-control and business-logic bugs, and proves confirmed findings with the request and response. You can start a pentest yourself, and data stays in Sweden.
Who Pentera is best for
Choose Pentera if you need to know whether an attacker who gets onto your network can reach domain admin, crack passwords or move through cloud identities. It covers internal networks and Active Directory, where Barrion doesn't test at all, and it runs agentless across the whole estate.
Frequently asked questions
Is Barrion a Pentera alternative?
Not really, because they test different things. Pentera validates internal networks, Active Directory, the external attack surface and cloud identity. Barrion pentests web apps and APIs, including logged-in testing as several users. Teams with both kinds of risk usually run one of each.
Does Pentera test web applications?
Pentera Surface lists internet-facing web applications among the external systems it tests (checked 2026-09-26). Its site centres on network, Active Directory and cloud identity validation rather than multi-role testing of web app logic, which is Barrion's focus.
How do the prices compare?
Pentera doesn't publish prices. Barrion's Essential plan starts at €199/month with per-run prices on the pricing page. Scheduled pentests are on the Business plan, priced through sales.
What about Horizon3.ai NodeZero?
NodeZero is in the same category as Pentera: autonomous pentests of internal and external networks, Active Directory, cloud and Kubernetes, with attack paths and proof of exploit. Unlike Pentera, it offers a free trial. Like Pentera, it's a network tool first.
Summary
These are two different layers, not two answers to the same question. Pentera validates your network, Active Directory and cloud identity. Barrion pentests your web app and APIs. A SaaS company with little internal network may only need Barrion. An enterprise with a large internal estate needs Pentera or Horizon3.ai NodeZero for the network and a web app tool for the product.
