What is a pen test?

What business penetration testing is — and why it matters

A penetration test is an authorized, simulated cyberattack. Instead of guessing where you're exposed, our testers actively try to break in using the same tools and techniques criminals use — safely, within rules you approve.

The result is proof: which weaknesses are real, how they could be combined, what data or systems an attacker could reach, and the specific steps to fix each issue.

What we test

Types of penetration testing we perform

Choose one, or combine several into a single engagement and report.

Web application penetration testing

Websites, customer portals, e-commerce stores, and internal web apps. We test authentication, session handling, access controls, input validation, business logic, and the full OWASP Top 10 — including SQL injection, cross-site scripting (XSS), and broken access control.

External & internal network penetration testing

External tests target everything facing the internet: firewalls, VPNs, email servers, and remote access. Internal tests simulate a compromised laptop or malicious insider, including Active Directory, file shares, and Wi-Fi.

Cloud penetration testing

AWS, Microsoft Azure, Microsoft 365, and Google Cloud. We look for misconfigured storage, over-privileged identities, exposed keys, and paths from the internet into your cloud account.

Learn more →

API & mobile app penetration testing

REST and GraphQL APIs and iOS/Android apps, following the OWASP API Security Top 10 and Mobile Application Security guidelines.

Social engineering & phishing simulation

Most breaches start with a person, not a server. We run realistic, pre-approved phishing campaigns and phone pretexting to measure how staff respond, then provide targeted training recommendations.

Who it helps

Who needs penetration testing?

If your business stores customer data, takes payments online, or answers security questionnaires from clients, a penetration test is one of the most valuable security investments you can make.

  • Businesses required to test for PCI DSS, HIPAA, SOC 2, or ISO 27001
  • Companies renewing cyber insurance policies that ask for recent test results
  • SaaS companies answering enterprise security reviews
  • Organizations launching a new website, app, or cloud migration
  • Any business that has never had an independent security test

Example engagement

Case study: regional dental group

SAMPLE CASE STUDY — replace with a real, permitted example

Challenge: A 6-location dental practice needed a penetration test for HIPAA risk analysis and its cyber insurance renewal.

What we found: A vulnerable patient portal login and an outdated VPN appliance that together could have exposed patient records.

Outcome: Both issues were fixed within two weeks, verified in our free retest, and the practice submitted the attestation letter with its insurance renewal.

Pricing

FAQ

Penetration testing FAQ

More questions? Call (727) 340-3921 or email us.

How long does a penetration test take?

Most small business engagements take 5 to 10 business days of testing, with your report delivered about a week after testing ends. Larger or multi-part scopes take longer; your quote will include a timeline.

What's the difference between a vulnerability scan and a penetration test?

A vulnerability scan is automated and lists possible weaknesses. A penetration test adds skilled manual testing to confirm which weaknesses are real, chain them together the way an attacker would, and show the actual business impact.

Is penetration testing legal?

Yes, when it's authorized. We never begin testing without a signed agreement from the system owner that defines exactly what may be tested and when.

What do I need to provide before testing?

A list of in-scope systems, a point of contact, and — for authenticated tests — test user accounts. We'll send a short onboarding checklist after you approve the quote.

Do you offer black-box, gray-box, and white-box testing?

Yes. We'll recommend the right approach during your consultation based on your goals and budget. Gray-box testing usually gives the best value for businesses.
