1. What is an automated pentest?
A penetration test (or pentest) means stepping into an attacker's shoes to check what they could realistically compromise on your information system. Traditionally, a consultant carries out this work by hand, over a limited period.
An automated pentest reproduces those same offensive techniques — discovery of exposed assets, exploitation of flaws, privilege escalation, lateral movement — but in a software-driven, repeatable way. The goal is not to replace human expertise on the most complex scenarios, but to make continuous, low-cost testing accessible — the kind of testing that used to be reserved for large enterprises.
For an SMB, the benefit is twofold: a predictable cost (a subscription rather than a per-engagement quote) and a high frequency, where a manual pentest happens once a year — at best.
2. Why traditional pentesting doesn't fit SMBs
The "per-engagement" pentest was designed for organisations with a security budget and dedicated technical contacts. Three obstacles stack up for an SMB:
- Cost. A manual pentest engagement usually runs into thousands of euros, which makes it hard to repeat several times a year.
- Lead time. Between scoping, execution and the report, several weeks go by — a pace that clashes with frequent releases.
- The one-off nature. An annual pentest only reflects security at a single point in time. A new dependency, an update or a changed configuration can reopen a breach the very next day.
Many SMBs then fall back on a plain vulnerability scanner — useful, but one that doesn't prove a flaw is actually exploitable (see section 4).
3. What an automated pentest actually tests
A serious automated pentest doesn't stop at listing CVEs. It chains together the same phases as an offensive team. At pentestaas, the engine runs four phases:
- Reconnaissance — mapping exposed assets, services and ports.
- Exploitation — real attempts to exploit the vulnerabilities identified.
- Post-exploitation — what an attacker would obtain once inside (access, data, privileges).
- Pivot — movement toward other machines reachable from the compromised foothold.
These phases draw on more than 200 attack modules, and every result is mapped to the MITRE ATT&CK framework so it can be read in a standard language. Findings are delivered as actionable reports (HTML, PDF, JSON) that rank risks by severity, with remediation steps.
4. Automated doesn't mean "vulnerability scanner"
This is the most common — and most costly — confusion. A vulnerability scanner detects potential weaknesses from signatures and version numbers. It often produces long lists, with false positives, without telling you which ones are actually exploitable.
An automated pentest goes further: it attempts exploitation. The difference is decisive for an SMB that has to prioritise a limited budget:
- A scan says: "this service has a known vulnerability."
- A pentest says: "this vulnerability is exploitable, here is what an attacker would obtain, here is how to fix it first."
Moving from detection to validation through exploitation avoids spreading effort across theoretical alerts and focuses fixes where the risk is concrete.
5. One-off or continuous: which to choose?
A one-off pentest still makes sense at a key moment: before launching a new service, during an architecture change, or at a partner's request.
But for an SMB whose system evolves regularly, continuous testing is a better fit: it replays the same attacks at regular intervals and catches regressions as soon as they appear, rather than twelve months later. That is exactly what a subscription model makes possible, where a one-off engagement would quickly become unaffordable if repeated every month.
6. How to get started without in-house expertise
The point of a pentest as a service approach for an SMB is that it doesn't require offensive skills in-house: you declare the scope to test, the engine runs the phases, and the report turns the results into prioritised actions.
pentestaas offers this test on a self-service basis, starting at €250 excl. VAT per month, with no consultancy engagement. It's the entry point designed for organisations without a dedicated IT team that want an honest first picture of their exposure.
