Network infrastructure pen testing

Network infrastructure penetration testing is a comprehensive assessment that evaluates the security of your business network and system infrastructure. It involves an authorised, simulated attack on your network to identify vulnerabilities and assess the effectiveness of security controls. The goal of network infrastructure pen testing is to help you find and prioritise your security flaws before they’re discovered and exploited by a cyber criminal.

Bulletproof’s CREST-certified penetration testers employ the tools and techniques used by real-world hackers to evaluate your security and simulate a breach in a safe, controlled environment. Penetration tests are in high-demand from business of all sizes and sectors and form the basis of any cyber security strategy.

Benefits of network pen testing

Compromised data and systems damaged from a cyber attack can quickly lead to financial and reputational damage that’s often hard to recover from. Exploiting vulnerabilities in a controlled environment through CREST-certified network and infrastructure pen testing allows you to see where your security defences are failing and helps you prioritise improvements.

  • Uncover vulnerabilities and poor security controls
  • Exploit network security flaws in order to understand the full risk
  • Expose insecure functionality in your networks and logic flaws
  • Forms the basis of any cyber security strategy
  • Meet compliance requirements, including PCI DSS, GDPR and more

We know the threat landscape is dynamic and constantly evolving which is why we offer 12-months of free vulnerability scanning with every penetration test package.

Internal vs External Penetration Testing

Internal and external infrastructure testing provide two different models of what an attacker could damage within your network. Bulletproof recommends a blended test with internal and external assessment components for the best security outcome.

Internal Pen Tests

Internal pen tests can assess your more vulnerable internal network infrastructure. It’s usually a more in-depth test that models what an attacker could achieve if they were to get direct access to your internal network./p>

External Pen Tests

A pen test designed to test your external presence determines how easily your system can be breached with little to no information to gain access. Penetration testers start without any user privileges to internal systems.

Highlighting the most common vulnerabilities

Bulletproof penetration testers are all experienced ethical hackers with a wide knowledge of different network and infrastructure technologies. They use their insight and ingenuity to discover security flaws in your organisation. Here are the Top 10 most common internal & external network vulnerabilities we find:

  1. SSL Misconfigurations
  2. Missing HTTP Security Headers
  3. Outdated Website Libraries/Components
  4. SMB Signing not Required
  5. Excessive Information Disclosure
  6. Unnecessary Open Services
  7. Host Header Injection
  8. Outdated and Unsupported Third Party Software
  9. SSH Misconfiguration
  10. Click Jacking

of network vulnerabilities are easily fixed

of these will be exploited by cyber criminals

Here’s what our customers say about us

We approached Bulletproof as one of several suppliers who offer penetration testing services. Out of all those contacted, Bulletproof were by far the most professional and slick to work with. From start to finish, the whole process was painless and ran like clockwork. The conclusive pen test report was succinct with clear steps of resolution provided. We were genuinely impressed with how easy Bulletproof were to work with, and would definitely recommend.

Eleanor Blacklock KURVE, Product Manager

This was a very straightforward process. I had enough information up front to understand the process, and did not need to ask many questions along the way. Great service!

    Frequently asked questions

    Network application penetration testing is an infrastructure assessment of shared networks, testing both internal and external networks for flaws and vulnerabilities, analysing operational security levels for misconfigurations, design flaws, and to assess the effectiveness of security controls within the network.

    Network pen testing is a proactive approach to cyber security. It discovers, critically assesses and exploits security vulnerabilities, weaknesses and technical misconfigurations that a cyber attacker would target in your network’s infrastructure.

    The ramifications of a breach can be costly fiscally and reputationally. The number of cyber attacks on a business is on the rise so it isn’t a case of ‘if’ but ‘when’.

    Our network pen testing experts will identify the risks posed to your business, and crucially, develop a comprehensive plan to strengthen your cyber resilience. In as little as 3 days and with minimal disruption to your business, you’ll know how to bulletproof your organisation.

    • All risks based on the current server/ application setup/configuration
    • Vulnerabilities and running services for the servers and applications
    • What has been done to exploit each security issue
    • Remediation steps
    • Near-term and long-term actions

    All testing programmes are bespoke to your needs and organisation so please use the above as a guide.

    • Medium apps, networks, cloud systems: 5-10 days
    • Larger apps, networks, cloud systems:10 days+

    All tests are tailored to you so use this as a guide.

    Testing can be performed against a non-production replica of your live environment, such as a UAT/QA environment, to ensure no risk to your live services. If testing against production is unavoidable, we can coordinate our testing activities to minimise the impact. You can also specify things like no denial of service (DoS), meaning tests will have a negligible impact on your day-to-day operations.
