Penetration Testing in 2026: What It Costs, What It Covers, and How to Actually Use the Results

Every compliance framework — SOC 2, ISO 27001, HIPAA, PCI DSS — requires some form of vulnerability assessment or penetration testing. But most companies overpay for pentests they don't fully understand, then shove the report in a drawer until their auditor asks for it.

Let's fix that.

What is a Penetration Test, Really?

A penetration test (pentest) is a simulated cyberattack against your systems to identify exploitable vulnerabilities. Unlike a vulnerability scan (automated), a pentest combines automated tools with manual testing by security experts who think like attackers.

Vulnerability scan vs. penetration test:

For most startups, you need both: continuous vulnerability scanning (which Proveably handles) plus a periodic penetration test.

Types of Penetration Tests

External Network Pentest

Tests your internet-facing infrastructure — the same attack surface that real attackers see first.

What gets tested:

• Web applications and APIs
• DNS configuration and zone transfers
• Email security (SPF, DKIM, DMARC)
• SSL/TLS configuration
• Open ports and services
• Cloud infrastructure (S3 buckets, Azure blobs, GCP storage)

Best for: SOC 2 compliance, general security validation

Internal Network Pentest

Simulates an attacker who has already gained access to your internal network (or a malicious insider).

What gets tested:

• Active Directory / LDAP weaknesses
• Lateral movement opportunities
• Privilege escalation paths
• Internal application vulnerabilities
• Network segmentation effectiveness

Best for: Companies with on-premises infrastructure, PCI DSS requirements

Web Application Pentest

Deep-dive into your web application's security — the most common type for SaaS companies.

What gets tested:

• OWASP Top 10 vulnerabilities (injection, XSS, broken auth, etc.)
• API security (authentication, authorization, rate limiting)
• Business logic flaws
• Session management
• File upload vulnerabilities
• Information disclosure

Best for: SaaS products, e-commerce, any customer-facing web application

Cloud Configuration Review

Evaluates your cloud infrastructure for misconfigurations that could lead to data exposure.

What gets tested:

• IAM policies and roles (overly permissive?)
• Storage bucket policies (publicly accessible?)
• Network security groups and NACLs
• Logging and monitoring configuration
• Encryption settings
• Secrets management

Best for: AWS, GCP, or Azure environments. Overlaps significantly with what Proveably's automated cloud scanning covers.

Mobile Application Pentest

Tests your iOS and Android applications for platform-specific vulnerabilities.

What gets tested:

• Data storage security (keychain, shared preferences)
• Network communication (certificate pinning)
• Binary protections (obfuscation, anti-tampering)
• Authentication implementation
• API communication

What Does a Pentest Cost in 2026?

Here's the honest pricing breakdown:

What makes it more expensive:

• Number of IP addresses / domains in scope
• Number of user roles to test
• Complexity of business logic
• Compliance requirements (PCI DSS has specific pentest requirements)
• Retesting after remediation

What you can do to reduce costs:

1. Run your own vulnerability scans first. Fix the easy stuff before paying a pentester $200/hour to find it. Proveably's continuous scanning catches the low-hanging fruit automatically.
2. Define scope tightly. More IPs and applications = higher cost.
3. Provide documentation. API docs, architecture diagrams, and test accounts save the pentester time.
4. Fix and rescan before retesting. Many firms charge extra for retest rounds.

How to Read a Pentest Report

A good pentest report should include:

Executive Summary

• Overall risk rating
• Number of findings by severity
• Key recommendations (2-3 sentences a CEO can understand)

Methodology

• Tools used (Burp Suite, Nmap, Metasploit, etc.)
• Testing approach (OWASP, PTES, OSSTMM)
• Scope and limitations

Findings (the meat of the report)

Each finding should have:

## Finding: SQL Injection in User Search API

**Severity:** Critical
**CVSS Score:** 9.8
**Location:** POST /api/v2/users/search
**Parameter:** query

### Description
The user search endpoint is vulnerable to SQL injection via the
`query` parameter. An authenticated user can extract the entire
database contents, including user credentials and PHI.

### Proof of Concept
POST /api/v2/users/search
Content-Type: application/json
{"query": "' UNION SELECT username, password FROM users--"}

### Impact
Complete database compromise. Attacker can read, modify, or delete
all data including customer records and credentials.

### Remediation
- Use parameterized queries / prepared statements
- Implement input validation with an allow-list approach
- Apply WAF rules to detect SQL injection patterns
- Review all database queries for similar issues

### Reference
- CWE-89: SQL Injection
- OWASP: https://owasp.org/Top10/A03_2021-Injection/

Remediation Priority Matrix

The best pentests give you a prioritized fix list — not just a dump of findings. At Proveably, we automatically map pentest-style findings to compliance controls, so you know which fixes unlock compliance progress.

How to Use Pentest Results for Compliance

Different frameworks have different pentest requirements:

SOC 2

• Requirement: Risk assessment must include vulnerability testing
• Frequency: At least annually
• What auditors want: Evidence that you tested, found issues, and remediated them
• Pro tip: Your Proveably scan results combined with a focused manual pentest satisfy this requirement

PCI DSS

• Requirement: Quarterly vulnerability scans (ASV) + annual pentest
• Frequency: Quarterly scans, annual pentest
• What's specific: Must follow PCI DSS pentest guidelines, test segmentation controls
• Important: External scans must be done by an Approved Scanning Vendor (ASV)

ISO 27001

• Requirement: Technical vulnerability management (A.8.8)
• Frequency: Risk-based (but auditors expect at least annual)
• What auditors want: Evidence of a structured vulnerability management programme

HIPAA

• Requirement: "Technical evaluation" per §164.308(a)(8)
• Frequency: When significant changes occur (and periodically)
• What auditors want: Evidence that you assess your security controls regularly

Continuous Scanning vs. Annual Pentests

The industry is shifting from annual pentests to continuous security validation. Here's why:

The problem with annual pentests:

• Your infrastructure changes daily; a pentest is a snapshot
• You ship code weekly; the pentest tested last month's code
• Attackers don't wait for your annual pentest schedule
• 364 days of the year, you're running unvalidated

The modern approach:

1. Continuous automated scanning (Proveably) — daily/weekly vulnerability detection
2. Annual penetration test — deep manual validation
3. Event-triggered testing — after major releases or infrastructure changes

This approach satisfies every compliance framework AND provides genuinely better security.

Choosing a Pentest Firm

Look for these qualities:

• Relevant certifications: OSCP, OSCE, GPEN, GXPN
• Industry experience: Have they tested SaaS products like yours?
• Clear methodology: PTES, OWASP, or a documented custom approach
• Sample report: Ask to see a redacted report before committing
• Retest included: Good firms include one retest round in their price
• Communication: Will they call you immediately if they find something critical?

Red flags:

• No named testers (just "our team")
• Automated-only results dressed up as manual testing
• No proof of concept for findings
• Refuses to share methodology
• Pricing that's too good to be true (you'll get a tool dump, not a pentest)

Fix the automated findings before your pentest begins, so your pentester spends time on the complex, high-value manual testing — not rediscovering that your TLS configuration is outdated.
