Secure · Application & Device Penetration Testing

Will this app or device hold up before our customers and auditors test it for us?

We test web apps, APIs and connected devices by hand, chain small findings the way an attacker would, and review code while fixes are still cheap.

The Vizius Way

How it works: five steps, one Principal Engineer

One Principal Engineer leads it from the first call until your team has adopted the work and trusts it. Each step shows what it means for this engagement.

  1. Step 01

    Discovery Call

    30 minutes with the Principal Engineer who would lead this engagement. Free, and no sales handoff.

  2. Step 02

    Direct Assessment

    ScopeAgree the build, roles, environments and test accounts.

    Test during developmentTest early builds so fixes land before release, not after.

  3. Step 03

    Shared Roadmap

    Collaborative definition of top priorities.

  4. Step 04

    PE-Led Delivery

    Report and fixDevelopers get specific, reproducible findings and can ask our testers questions.

  5. Step 05

    Outcome Assurance

    Retest and summarizeWe confirm the fixes and issue a customer-facing summary.

How we work, step by step

Proof

What changed for a client

A bank-software vendor tested its rewrite three times during development and shipped with no high-severity findings.

Secure

In their words

Clients' own words, shared with their permission. Some chose to name their company.

Collaborating with Vizius feels like having a seamless extension of our own team, particularly when it comes to their expertise in cybersecurity and web application security. The recent penetration test engagement has yielded valuable insights that fuel ongoing improvements in Barchart's cybersecurity initiatives, ultimately boosting our confidence in our security measures.

Who you'll work with

A Principal Engineer, not a salesperson

Likely lead: Glenn Johnson or David Frazer. You talk to the engineer who does the work on Application & Device Penetration Testing.

Questions buyers ask

Can you test before launch?

Yes, and it is cheaper. One client tested its rewrite three times during development and shipped with no high-severity findings.

Do you test devices and firmware?

Yes. We have tested printer platforms and other connected equipment against product security requirements such as IEC 62443, testing one device per family to save time and cost.

Will we get something customers accept?

You get a full report for your team and a summary letter written for customers and auditors.

More detail

Scanners miss business-logic flaws. We do application penetration testing on web apps and APIs, and embedded software penetration testing on connected devices and their firmware. We test by hand, chain small findings the way an attacker would, and review code and development practices while fixes are still cheap. You ship with evidence your customers and auditors will accept.
