Your product runs on code, APIs and cloud infrastructure, exactly where attackers look first. A flaw in authentication, in permissions or in the isolation between customers can expose all of your users at once. We test your platform the way a real attacker would, and tell you exactly what could be exploited.

When a company works with your software, it hands you its data and a piece of its own security. Badly handled permissions or a leaked token on your platform are not only your breach: they are a way in to every customer sitting on top of it.
In a modern SaaS platform, the risk is rarely one dramatic bug. It is usually one of these:
What one customer can see or touch of another’s data when multi-tenancy fails.
Which endpoints let permissions be bypassed to reach data or actions they should not.
Where the trust between your platform and your customer’s identity provider breaks.
What your platform inherits when it connects to another company’s stack.
An enterprise buyer puts your security under a microscope before signing, and a recent pentest with a clean retest answers a large part of it.
A penetration test is a standard expectation behind a strong SOC 2 report, and your assessor expects traceable scope and retest evidence.
The APIs behind your product are the main way in, and a new one exposes authorisation logic that a scanner cannot judge.
A change to the multi-tenant architecture moves the line between one customer’s data and another’s. If that separation fails, one account opens the rest.
It is the standard your customers and their procurement teams recognise, and the pentest is the technical evidence behind the certificate.
Every third party you connect and every access grant widens your attack surface, and they often carry far more access than they need.
When a supplier you depend on falls, the question is not whether you have findings, but which path is still open to your customers’ data.
Whether it is a multi-tenant SaaS, a public API, a developer platform or a connected ecosystem, we define the scope, the schedule and the consultant who will run your project together. The same person who runs the tests is with you from the first call.
Real advisories from CISA, in products used across the Tech & SaaS sector.

We at Etnia highly value our collaboration with Asperis Security. Their professionalism, approachability, quick response and ability to adapt to our needs have been key in every project. The quality of service and continuous support always give us peace of mind. Without a doubt, it is a pleasure to have them as technology partners.
At NPAW we have collaborated with Asperis on various security initiatives and the experience has been very positive. We especially value their ability to adapt to our needs and the depth with which they approach each project. Results are clear, structured and useful for decision-making and continuous security improvement. We like working with Asperis for the judgment and value they bring to every collaboration. Their work has helped us strengthen our security level.
ASPERIS has worked alongside us to define and implement our cybersecurity roadmap in Microsoft 365 with a structured approach aligned to business objectives. Thanks to their advice, we took the strategic step of completing our Microsoft ecosystem and reinforcing it with CrowdStrike for advanced mobile device protection, significantly raising our security level.
With Asperis you don’t hire a service. You hire a partner. They don’t look to bill a project. They look to establish a relationship of trust, caring about the key points that affect your organisation’s security. Professionalism, know-how and diligence.
Seven questions we hear in every SaaS introductory meeting. If yours isn’t here, ask it.
The most common serious problem is one customer being able to reach another customer’s data, along with weak access control, over-exposed data, and old endpoints left live in production after everyone forgot about them. These are logic and access problems a scanner cannot judge, which is why we test them by hand.
Yes. We test your single sign-on, the apps connected to it and the access each one is granted, along with the ways an attacker could abuse them to reach data or take over an account. In SaaS, this is often where the real risk lives.
You test continuously instead of once a year. Through our platform, testing and retests run as your product changes, so your security keeps pace with your release cycle rather than reflecting how things looked last spring. It is the model built for teams shipping constantly.
Yes, directly. A penetration test is a standard expectation behind a strong SOC 2 report and a recognised piece of evidence for ISO 27001, and a recent test with a clean retest answers a large part of most vendor security questionnaires. We provide the technical testing and the evidence; the SOC 2 attestation and the ISO 27001 certificate themselves come from your assessor and certification body.
No, not without your explicit consent. Every engagement runs under documented Rules of Engagement: agreed windows, limits, forbidden actions and a coordination channel. We do not use disruptive techniques unless they are specifically authorised, so you get an attacker’s view without risking your platform or your customers.
A technical contact, a clear scope, and access to a suitable environment. For a grey-box test, the usual choice, we ask for test accounts across your roles and API documentation (OpenAPI or a Postman collection) if you have it. We bring the tooling, the test data and the reporting.
You get an executive and technical report, a prioritised remediation guide, a certificate of execution, and a retest with documented closure evidence, all exportable from the platform. The summary and certificate are made to share with a prospect or an auditor without exposing sensitive detail.
A security flaw in your platform does not only put your data at risk: it puts at risk the data of every customer who trusts you. We test your product the way a real attacker would, so that you find the flaws before someone with worse intentions does.
