Secure · Network Penetration Testing

If someone got onto our network, how far could they get?

We find the few attack paths that matter, rank them by risk, and retest after you fix them. Annual or continuous.

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

    Scope call30 to 60 minutes with a Principal Engineer to agree targets, rules and dates.

    TestTypically one to three weeks of hands-on testing. Serious findings are raised the day we find them.

  3. Step 03

    Shared Roadmap

    ReadoutA plain-language report and a working session with IT and leadership.

  4. Step 04

    PE-Led Delivery

    Your PE owns the engagement, end to end.

  5. Step 05

    Outcome Assurance

    RetestWe test the fixes and update your grade.

How we work, step by step

Proof

What changed for a client

A real estate developer moved from a D to an A- protection grade across three tests (2022 to 2025).

Secure

In their words

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

We just finished an engagement with Vizius and would highly recommend them. They did a technical risk assessment and pen test across our entire tech stack - their report and feedback was very thorough, and they worked hand in hand with us the whole way through remediation. They're a great team, and I have peace of mind knowing we're able to protect our clients and their data. If you have sensitive data you need to protect and are due for this service, I'd highly recommend Vizius!

What you get

  • External and internal testing, scoped to the systems that matter to the business
  • Protection and detection graded separately, so you see what your MSP or SOC does well and where attackers get in
  • A short list of attack paths, each tied to a business consequence and a practical fix
  • A retest of what you fixed, and a grade you can track year over year
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 Network Penetration Testing.

Questions buyers ask

How is this different from a vulnerability scan?

A scan lists known weaknesses. A tester chains them together to show what an attacker could actually reach, such as a printer that leads to domain administrator.

Will testing disrupt operations?

We agree rules of engagement first, avoid fragile production and OT systems unless you ask us to include them, and stop to call you if something looks risky.

Do you retest?

Yes. Retesting the fixes is part of how we work, because an unverified fix is still a guess.

More detail

In network penetration testing, also called infrastructure penetration testing, our testers attack your perimeter and internal network the way a real intruder would, including the printers, cameras and building systems nobody counts. You get the few attack paths that matter, ranked by business risk rather than scanner severity, and a retest that shows they are closed. Run it once a year or continuously.
