The MSS Difference

MSS has built a reputation for high levels of responsiveness, a focus on proactive client management and delivering the best outcomes for our clients.

Working across both the public and private sectors, MSS operates in industries dependent on accreditation and in which there is increasingly onerous regulation. Our teams are skilled, highly trained and demonstrate proven project-management capabilities, and long-standing client and stakeholder relationships. The group's consultancy-led approach is another key differentiator and means our clients are able to easily access a broad range of technical expertise and services under one roof.

We operate in sectors where the buying criteria is broadly similar. Typically, MSS customers have interesting needs, requiring the ability to overcome challenging logistical and technical problems. There are high barriers to switching provider for many clients, and key selection and retention factors include the experience and capability to deliver exceptional standards in business-critical scenarios.
