Securing and rehosting a business-critical application service
Assessing, remediating and transitioning an application stack into a secure managed environment
Read Time
A UK-based organisation relied on a business-critical application stack to support day-to-day operations. The application was also important to work involving UK Government departments, which meant security, assurance and operational confidence were central to its continued use.
The application had originally been developed with a strong focus on user functionality. Over time, security had not been treated with the same level of priority. As the service became more operationally significant, the organisation needed to understand the security position, remediate weaknesses, support assurance activity and transition the application into a more secure hosting environment.
Logiq was engaged to assess, remediate, assure and rehost the application stack.
The application supported important operational activity, but its security posture needed to be improved. The client required a clear understanding of the risks across the application stack, a practical remediation plan and support through the assurance process.
The challenge was not only technical. The application involved several stakeholder groups, including the client, UK Government stakeholders and a third-party application developer. Any remediation activity needed to consider operational continuity, user functionality and the need for a controlled transition.
The client needed to reduce security risk without degrading the service or disrupting users who relied on it.
Logiq began with a security assessment of the application stack, considering recognised application security principles and relevant government guidance. The assessment looked beyond purely technical vulnerabilities and considered wider operational, procedural and stakeholder-related risks.
Following the assessment, Logiq produced a practical remediation roadmap. This set out what needed to be addressed, how work should be prioritised and how changes could be made without undermining the functionality of the application.
Logiq then worked with the client, government stakeholders and the third-party developer to support remediation activity, update security documentation, prepare assurance evidence and plan the rehosting of the application into Logiq’s secure managed environment.
Logiq provided a complete package of security assessment, remediation support, assurance activity, rehosting and transition support.
The engagement included an initial security assessment against recognised application security considerations, identification of operational and socio-technical risks, development of a remediation roadmap, support to resolve security issues with relevant stakeholders, updates to the Security Management Plan, security architecture and risk management support, functional testing ahead of transition, rehosting into a secure managed environment, and support through service transition.
The work combined security, risk, project delivery and development expertise, allowing the client to address the application as a live operational service rather than as a purely technical asset.
The application stack was remediated, assured and transitioned into a secure managed environment. The client and relevant government stakeholders gained greater confidence that security risks had been identified, addressed where practical, and placed under a more proactive through-life management model.
The service continued to support operational activity, with security managed as part of its ongoing lifecycle rather than treated as a one-off remediation exercise.
Business-critical applications often evolve over time. They may begin with a focus on functionality, then later become more important, more connected or more exposed than originally expected. When that happens, security cannot be improved through isolated technical fixes alone.
This engagement showed how Logiq can help clients assess, remediate, assure and manage important application services through life. The value was in combining security expertise with delivery discipline, stakeholder coordination and a hosting model designed to support ongoing risk management.
