    Free Retesting

    The clear majority of penetration testing companies charge over £1000 a day to retest an environment. Our penetration testing service comes with free retesting for all penetration testing assessments.

    Our penetration testing services are tailored to provide the best solutions at competitive prices, ensuring protection for companies of all sizes. No company should be priced out of security.

    GDPR Penetration Testing

    A GDPR penetration test ensures your company is compliant with article 32(1.d) of the General Data Protection Act which states that any process that handles data must have its security evaluated and a process of regular testing must be in place. The purpose of this is to make sure that data within that application/system is secure and not vulnerable to a data breach.

    What do we test for?

    In a GDPR penetration test, the data held within the application is given special attention. We run tests to see if personal information is public when it shouldn’t be, and if an attacker can benefit from it. 

    Depending on the type of system being tested, penetration testing methodologies such as OWASP, NIST, and PTES will be utilised, identifying not only flaws with personal data storage, but also vulnerabilities in the system itself.

    What are the risks?

    The risk to the environment and personal data without a penetration test can be quite severe with around 1 in 4 applications having a critical flaw that is discovered during a pen test. This could lead to a data breach as well as a fine from the Information Commissioner’s Office (ICO) for not taking protective measures and securing data correctly. These fines can be up to €20 million or 4% of your gross annual revenue (whichever is highest).

    Ensuring your customers’ data is secure within your applications and infrastructure and while it is being processed can ensure that you and your customers are protected from any future breaches.

    Frequently Asked Questions

    What is Article 32 (1) of GDPR?

    Article 32 of the GDPR mandates that businesses take technical steps to safeguard data protection. Despite the fact that the article provides examples of security measures, it does not provide a complete list. In light of the continually evolving information security threat landscape, businesses must evaluate, implement, and maintain appropriate security measures.

    Article 32 (1) states the following measures must be applied:

    – The pseudonymisation and encryption of personal data.
    – The ability to ensure the ongoing confidentiality, integrity, availability and resilience of processing systems and services.
    – The ability to restore the availability and access to personal data in a timely manner in the event of a physical or technical incident.
    – Process for regularly testing, assessing and evaluating the effectiveness of technical and organisational measures for ensuring the security of the processing.

    Source – Article 32 (1) – General Data Protection Regulation

    As explained by the ICO “The UK GDPR specifically requires you to have a process for regularly testing, assessing and evaluating the effectiveness of any measures you put in place. What these tests look like, and how regularly you do them, will depend on your own circumstances.” – Article 32 (1) – ICO

    Is Penetration Testing required to comply with GDPR?

    Organisations must comply with a number of requirements under the GDPR in order to protect personal information and not risk considerable financial and reputational harm. One such need is to test your information security procedures on a regular basis to guarantee that they stay effective and up-to-date. One way to ensure you have taken appropriate measures is to conduct Penetration Testing.

    How much does a GDPR penetration test cost?

    All types of penetration testing differ in methodology and price. There are a number of factors that go into setting a price for a penetration test, including expenses for the tester and the types of assets being tested. A smaller application will take considerably less time than a large, complex commercial application. We aim to make our pricing as flexible as possible. Sencode will provide our best judgement via accurately scoping your digital assets and making a determination based on our experience testing similar scale assets. Once we have accurately scoped your project, we can provide a project proposal and a quote which will be costed appropriately.

    Example 1: A medium sized finance web application comprised of 35 unique pages with user and case management. 5 days of penetration testing. £3000-£4000
    Example 2: An external infrastructure penetration test comprised of 10 unique IP addresses. 2 days of penetration testing. £1000-£2000
    Example 3: An internal penetration test on 80 IP addresses, 7 days of penetration testing. £5500 – £6500

    These prices are variable based upon; Number of IP Addresses being tested, Retesting requirements, After-hours testing and skills required to conduct the engagement

    Who should get a GDPR Penetration Test?

    For a medium-sized business, a complete GDPR testing programme might include the following:

    – Regular internal and external vulnerability scans.
    – Annual penetration testing of all GDPR relevant infrastructure, or ad hoc penetration testing after large scale amendments to your digital assets.
    – Simulated phishing attacks should be conducted on a regular basis to identify any training gaps which could then covered by Cyber Awareness Training.
