Why have a vulnerability assessment?

Vulnerability assessments deliver an effective approach to identifying and mitigating the impact of a potential cyber threat and to provide your organisation with insights into where it can improve its threat exposure and system and platform hardening.The key benefits of scanning your business network or web application for vulnerabilities are:

  • Fast identification and classification on security vulnerabilities/weaknesses 
  • Establishing best practice vulnerability management throughout your digital estate 
  • Reduced risk of security vulnerabilities leading to a successful cyber attack 
  • Proactive identification of potential impacts  
  • Single point of contact for management of vulnerabilities with an experienced cyber security professional  
  • Consultation on remediation of identified vulnerabilities, broken down into a comprehensive and easy-to-follow approach, this can be

ConnectDS provide a wide coverage for assurance with our 3 main types of vulnerability assessments requirements, these are:

  • Internal Network Assessment – Vuln assessment of internal devices using specialist assessment software and experienced security professionals to identify issues and deliver actionable vulnerability analysis insight for your organisational cyber risk management program. The implementation of internal scanning agents facilitates remote assessment of internal assets without the requirement for physical access or set-up of corporate VPN access; alternatively, on-site hardware can be provided.
  •  External Network Assessment – The vulnerability assessment tests the external network security, systems, applications and infrastructure devices to identify weaknesses that can be leveraged by attackers to gain unauthorised access to your systems. No additional hardware sensors or installation of software by the customer is required for this type of assessment.  
  • Web Application Assessment – The standard service provides monthly scans of the web application testing in-line with the OWASP Top 10 framework, including identification of the following vulnerabilities:
    • Cross-Site Scripting (XSS)
    • SQL injection  
    • Blind SQL injection  
    • Insecure cryptographic solutions 
    • Insecure session management 
    • Server configuration issues
    • Incorrect header information  
    • CRLF injections  
    • Command execution  
    • Format string exceptions  
    • Unvalidated redirects   

If you need an even more in depth analysis of your current cyber-security posture that can help you measure the actual risk to the business then our web application vulnerability assessment services can be coupled with our thorough our network penetration testing or web application Penetration Testing services to provide full organisation coverage and or on an ongoing basis.

ConnectDS’s UK vulnerability assessment service is a consultative engagement and includes detailed and overview reporting that includes security findings and remediation details in simplified format, all engagements also include a rescan for validation of remediated vulnerabilities. All consultation and advice will be provided for remediation of any identified vulnerabilities by one of our expert security professionals.

A vulnerability assessment is a security assessment that identifies all potential vulnerabilities on a network or computer system but does not manually validate or exploit these findings.

Costs of vulnerability assessments vary depending on the number of IPs that require testing. Please get in contact for more information on this.

Our vulnerability assessments include scanning, manual checks, reporting and consultation with an experienced cyber security professional.

Vulnerability assessments are important as they allow your business to identify and remediate potential flaws in your network security.

A vulnerability scan is used to identify vulnerabilities on a computer system, an assessment includes scoping, reporting and actionable insight / consultation.

We recommend performing vulnerability assessments at least once a year or every time there is a major change to your network infrastructure.

Unlike an automated vulnerability scan, penetration testing requires manual testing by skilled security professionals and is used to stimulate a real life cyber attack, exploiting vulnerabilities found.

GDPR does not strictly mandate the need for vulnerability assessments; however, they are vital in maintaining security hygiene and identifying any unwanted data exposure which could breach GDPR regulations.
