What is an Infrastructure Assessment?

Weaknesses within your network infrastructure are used by cyberattackers to gain entry to protected resources – like personal data or financial systems. Once inside your network, attackers can exfiltrate data, extort money or cause general disruption and destruction.

An infrastructure assessment probes your network nodes and software, identifying vulnerabilities before they are exploited. Using the same tools and techniques as the criminals, Fidus consultants scan and analyse every aspect of your infrastructure searching for weaknesses that need to be addressed.

Why Perform an Infrastructure Assessment?


Prioritised action plan

An infrastructure assessment will identify and prioritise vulnerabilities. The test results report includes an action plan so you know what to address first.


Check your security provisions

Your network will already include a number of security provisions – but are they still effective? An infrastructure assessment will confirm their effectiveness and advise on potential improvements that could be made.


Routine system testing

Some frameworks, like PCI DSS, demand regular testing of security provisions. Infrastructure assessment services from Fidus will ensure you meet your compliance requirements and achieve the necessary certifications.


Protect your customers

Customers are increasingly concerned about how their personal data is treated by businesses. Infrastructure tests prove that you are taking customer privacy seriously.


Secure your corporate reputation

As well as fines and costs associated with network infrastructure breaches, your corporate reputation will also suffer. Fixing problems before they are exploited will keep customers on board – and help to attract new ones too.

Our Approach

Assume you’ve already been compromised

Fidus consultants start every infrastructure assessment from the assumption that your network has already been breached. We search for potential weaknesses at the node level and the tell-tale signs that they have already been exploited.

Full software audit

Every application represents a potential attack surface. The Fidus team will audit all of your software assets, paying special attention to those applications which are out of date, or unsupported by the vendor. We can help you draw up an action plan for applying the necessary patches and bringing applications up to date.

Passwords, protocols and permissions

Every infrastructure assessment looks at passwords, protocols and permissions for servers, systems, applications and file stores. We help you identify misconfigurations, default credentials and improperly secured files that provide easy access for criminals.

Going beyond automation

To reduce the chance of risk factors being missed, Fidus combine automated vulnerability scanning tools with the knowledge and experience of their consultants. This is exactly the same approach adopted by cybercriminals, giving Fidus infrastructure assessments – and results – increased credibility.
