Frequently asked questions
Answers to the questions we hear most. Still unsure how it applies to your environment? Our engineers are happy to talk it through.
What is the difference between external and internal penetration testing?
External testing simulates an attacker with no prior access trying to break in from the internet. Internal testing simulates an attacker, or a malicious insider, who already has a foothold inside your network. Together they show both how attackers get in and what they can do once they are inside.
Do I need both, or just one?
Most organizations benefit from both. External testing protects your perimeter, while internal testing reveals what happens if that perimeter is ever bypassed, whether through phishing, a stolen device, or an insider. Many compliance frameworks expect both to be tested regularly.
How often should we run these tests?
At a minimum, once a year, and after any major change to your network, applications, or infrastructure. Organizations in regulated industries or handling sensitive data often test more frequently.
Will internal testing disrupt our network or daily operations?
No. We plan internal testing carefully with your IT team, schedule activity around business hours that work for you, and avoid any techniques that could cause instability in production systems.
What do we receive at the end of the engagement?
A detailed report covering every validated finding, risk ratings based on real business impact, evidence of exploitation where relevant, and clear remediation guidance. We also offer a retest to confirm fixes worked.
How long does an engagement take?
Most external and internal penetration testing projects take one to three weeks, depending on the size of your environment and the scope agreed during planning.
