Nessus vs Hydrostatic Pressure Test

The vulnerability scanner that makes you feel both secure and slightly paranoid about your entire network meets the ultimate 'trust but verify' for pressure systems. Here's our take.

Nessus

Nice Pick

The vulnerability scanner that makes you feel both secure and slightly paranoid about your entire network.

Pros

• Extensive vulnerability database with frequent updates
• Detailed reports with actionable remediation steps
• Supports compliance scanning for standards like PCI DSS and HIPAA

Cons

• Can be resource-intensive and slow on large networks
• Licensing costs add up quickly for enterprise use

Hydrostatic Pressure Test

The ultimate 'trust but verify' for pressure systems. Because nobody wants a surprise leak at 1000 PSI.

Pros

• Highly reliable for detecting leaks and structural weaknesses in closed systems
• Uses water as a safe, non-toxic, and cost-effective testing medium
• Provides clear pass/fail results with minimal risk of catastrophic failure during testing

Cons

• Requires significant setup time and equipment, including pumps and pressure gauges
• Not suitable for systems that cannot tolerate water exposure or require dry testing

The Verdict

Use Nessus if: You want extensive vulnerability database with frequent updates and can live with can be resource-intensive and slow on large networks.

Use Hydrostatic Pressure Test if: You prioritize highly reliable for detecting leaks and structural weaknesses in closed systems over what Nessus offers.

The Bottom Line

Nessus wins

The vulnerability scanner that makes you feel both secure and slightly paranoid about your entire network.
