Free initial consultation

We offer a free initial consultation to all our clients. This session allows us to understand your unique security posture, discuss your concerns, adapt our approach to meet your specific needs and provide a tailored and competitive quote for our services.

Free retesting of identified findings

Following the testing, assessment and identification of any weaknesses and vulnerabilities, we extend our commitment to your cybers ecurity by offering a free retest of any identified findings. This ensures that any vulnerabilities discovered during the initial assessment are effectively addressed, reinforcing the security of your systems and providing evidence-based assurance at the end of the engagement.

Free remote remediation consultancy

Recognising the importance of not just identifying but also remedying security weaknesses, we provide complimentary remote remediation consultancy to help your IT or development team to address them. This service is designed to support your team in implementing the necessary changes, providing expert advice and guidance every step of the way.

Free certificate of testing

Upon completion of penetration testing, where no critical or high-risk findings are identified, or upon the full remediation and retesting of such findings, we issue a certificate of testing alongside the detailed report. This certificate can be shared with third parties, such as clients and partners, as a tangible demonstration of your commitment to cyber security without sharing the confidential details in the report.

Our Cyber Security Assurance Services

Web app penetration testing

Penetration testing of Web applications involves the identification of security weaknesses and vulnerabilities caused by insecure coding practices, misconfiguration and bugs. It is usually performed on a test instance of the application but can also be performed on live instances if required.

Infrastructure penetration testing

Infrastructure penetration testing identifies vulnerabilities and misconfigurations that can be exploited to obtain unauthorised access to data, systems or hosted applications. Specific testing activities and methodologies may differ depending on the scope and objectives of the infrastructure testing engagement.

API penetration testing

More and more applications depend on publicly accessible Application Programming Interfaces (APIs) to provide their core functionality as well as to integrate with or extend other applications and data sources. With all the versatility and features of APIs come potential security weaknesses and vulnerabilities.

Security engineering & design

Security engineering is the methodological identification and specification of security requirements and their design and implementation in a given system or application taking into account its environment, users and business objectives.

Incident response & investigations

Incident response is a coordinated effort to rapidly respond to a security incident in the most efficient, cost-effective manner. The goal of incident response is to quickly identify an attack, minimise its effects, contain the damage, as well as identify and remediate the root cause of the incident to reduce the risk of future incidents.

Expert witness services (England & Wales only)

Expert witnesses are individuals who are recognised as authorities in their field and are called upon to provide their specialised knowledge and expertise in legal proceedings. They are typically called upon in court cases to provide opinions, analysis, and conclusions based on their expertise in a particular subject matter.

Codat has engaged Danielyan Consulting as our third party security consultant since the business first started in 2017.

Neil Thompson

CTO, WorkInConfidence

WorkInConfidence engaged Danielyan Consulting to carry out penetration testing on both our SpeakInConfidence and ReferenceInConfidence products. This took the form of an initial test to baseline where we were and then a second test after we had implemented recommendations from their report. Edgar was very good at explaining the process that was to take place and providing support as we got to grips with the outcome of his initial report. It was a very worthwhile exercise and we would definitely use Danielyan Consulting again for our future security testing.

Mattias Altin

CTO, Derivitec

Edgar was hired to perform a penetration test on the Derivitec Risk Portal in December 2014. I found Edgar to be very professional and diligent in his work and we were very happy with his analysis and follow-up report. I will continue to use his services in the future and would highly recommend him to other companies.

Paul Brown

Technical Lead, ELBI

Edgar was recommended to me by a friend and colleague, as a knowledgeable and trustworthy advisor and consultant on security matters. Edgar has helped Elbi Digital advance the security of its platform by providing security consultation and expert external application penetration testing. As part of his consultancy he educated and advised the whole tech team on processes and software solutions to make the platform as secure as possible against the OWASP Top 10 at launch, and to remain as secure as possible in the future.
