What is penetration testing?

A penetration test is a simulated cyberattack against your computer system to check for exploitable vulnerabilities. Unlike automated scans, it involves human experts attempting to breach your application, network, or cloud infrastructure defenses to provide a realistic assessment of your security posture.

Why do companies need penetration testing?

Companies need penetration testing primarily for two reasons: compliance and security. Many regulations like SOC 2, PCI DSS, and HIPAA mandate regular pentesting. Beyond compliance, it's a critical practice to uncover security weaknesses before malicious attackers do, protecting customer data and company reputation.

What is Pentest as a Service (PtaaS)?

Pentest as a Service (PtaaS) is a modern delivery model for penetration testing that uses a software platform to streamline the entire process. This includes scoping projects, communicating with testers, receiving findings in real-time, and integrating results into developer tools like Jira, which is often faster and more efficient than traditional, PDF-based consulting engagements.

How to choose

1. 1First, define your primary goal: are you testing for a specific compliance standard like SOC 2 or trying to find deep, unknown flaws in a new product feature?
2. 2Second, evaluate the provider's reporting and remediation workflow; ask for a sample report and check if they integrate with your team's tools like Jira or Slack.
3. 3Finally, interview the proposed testing team to verify their specific expertise matches your technology stack (e.g., AWS serverless, Kubernetes, iOS mobile).

What is the average cost of a penetration test?

The average cost of a penetration test varies widely based on scope, but typically ranges from $5,000 for a simple mobile app to over $50,000 for a complex enterprise network. Most providers quote per project, so you will need to engage with their sales team for a precise figure based on the size and complexity of your target systems.

How long does a penetration test take?

A typical penetration test takes one to three weeks to complete, from kickoff to final report delivery. The initial scoping and contracting can add another one to two weeks. PtaaS platforms can sometimes shorten this timeline by streamlining the upfront administrative work.

What is the difference between a pentest and a vulnerability scan?

A vulnerability scan is an automated process that checks for known vulnerabilities, while a penetration test is a manual process where a human expert simulates an attack. Scans are good for frequent, broad checks, but a pentest is necessary to find complex business logic flaws and confirm if a vulnerability is truly exploitable.

How often should you get a penetration test?

You should get a penetration test at least annually, and also after any significant changes to your application or infrastructure. Many compliance frameworks like PCI DSS require annual testing. For companies with rapid development cycles, a quarterly testing cadence or a continuous PtaaS model is often recommended.
