Verify your defences against malicious attacks

Without robust security measures in place, business-critical networks can be left exposed to a wide range of attack methods, due to firewall misconfigurations, missing security updates or weak or default credentials.

Independent verification of your external perimeter and its security controls will significantly reduce the risk of a cyber-attack At the very least, this will result in significant disruption, with consequences potentially extending to irreparable financial and reputational damage.

What to test for

At least one vulnerability is found in the vast majority of external penetration tests. If these were to be exploited by cyber criminals, sensitive information could easily be stolen, altered or used to cause significant financial or reputational damage to your business.

In order to identify any weaknesses in your infrastructure it’s important to thoroughly test all points of entry into your network, including devices, internet-facing assets and full routes into your system via external networks. Any firewalls and security systems you already have in place should also be assessed.

Does my business need external network testing?

In short, yes – your business most likely has a firewall to protect it from cyber-attacks. But if it has been misconfigured or hasn’t been properly maintained with all the relevant security updates, your company is at risk. Even temporary changes made several months ago could still be live and exposing your organisation to cyber threats.

A penetration test provides independent verification that your external perimeter is secure.

Researchers from Rapid7 found that during 80% of external penetration testing engagements, at least one vulnerability was found. They also discovered that in 33% of their penetration tests, user credentials could be obtained – enabling an attacker to wreak havoc across an entire network.

If cyber criminals are able to access your network, they can easily steal or modify sensitive data or bring down your entire IT systems – causing unparalleled financial and reputational damage.

What happens during an external network test?

An external network test will use the most up-to-date tools and techniques employed by cyber criminals to assess your network for any issues.

Our expert team will then provide you with clear, actionable steps that you can take to improve security, and will guide you through these to ensure that your systems are as resilient as possible.

Which aspects of my infrastructure will you test?

We’ll assess your network for any security gaps across your entire infrastructure. This includes carrying out thorough testing of:

  • Any points of entry into your network, including devices and internet-facing assets
  • Full routes into your systems via an external network
  • Your firewalls and any security systems
