What We Do

We’ve got everything you need to secure your business or organisation

Security Architecture

We offer a complete security architecture as a service to all Clients wishing to know whether a current design has implemented procedures in-line with best security practices, or to ascertain whether your current Infrastructure requires further assessment from a security domain specialist from EHJ & SJ Consultancy.

Digital Technology Solutions

Working with leading Cloud providers, we can develop and provide secure IT solutions to meet your Infrastructure needs, which have a high availability and redundancy built into the design. We also provide and implement custom tooling used by many within the security domain to actively monitor and protect your environment to ensure the threat surface of an attack is reduced whilst utilising security features within our provided Cloud environment to ensure our solutions are protected.

Vulnerability Discovery

Understanding or complying with PCI-DSS and industry best practices often requires a network/web security assessment. At EHJ & SJ Consultancy, we can offer these services for both Network and Web Based Infrastructure and provide comprehensive solutions to mitigate vulnerabilities. We also offer a Vulnerability Management process, which can be adopted by any organisation.

Audit, Risk & Compliance

Pertaining an inventory or understanding what Assets an organisation possesses is often difficult, complex and hard to manage as part of a standard BAU lifecycle. EHJ & SJ Consultancy are an experienced consultancy that has worked with multiple organisations to determine the best way to assess and audit organisations to ISO 27001, Cyber Essentials, ISA 62443 and PCI-DSS. We also can perform gap analysis reviews on both Data Centre, Cloud and Critical Infrastructure if required.

Application Security & SecDevOps

Building security into the Software Development Lifecycle (SDL) is pivotal to ensuring vulnerabilities are mitigated from day 0 and that an application conforms to best security practices. We offer services to any business wishing for us to consult on how best to design your applications whether this be mobile or web based. We also offer a practical implementation on performing SecDevOps using our preferred approach to implementing security during continuous CI/CD pipeline deployments.

Systems Engineering

We offer a Systems architecture services for anyone wishing to align multiple disciplines within our service which we offer. Here at EHJ & SJ Consultancy we can manage and assess the risks involved in working on projects dealing with multiple domains.

Eduardo Martinez Barrios Santander Payments & Industry Oversight - Open Banking

Ensuring security was taken seriously and implemented on a project that had no regard for cyber security was attributed to EHJ & SJ Consultancy's input on the TMS programme. We successfully managed to undertake a full security audit of our suppliers design and have the ability to assess the risks to the overall safety profile.
