TNC has seen an increased demand from its customers wanting to source managed security services as part of a wider Telco sourcing process. In some cases, these security services have been relatively simple secure internet gateway services such as perimeter firewalling, IDS/IPS, and web filtering services hosted and managed by the telco service provider. However, over recent months there has been an increasing demand for more advanced cyber security protection to be sourced under a single network and security contract, services such as next gen application firewalls, external threat intelligence and dynamic remote access solutions with, in some cases, a managed security operations centre (SOC) to provide around the clock monitoring and security incident management. In this whitepaper TNC explores what a Managed Security Service is and if/why convergence into a single Managed Network and Security contract could be considered. 

Why are customers considering
Managed Security Services?

Managing the security of corporate networks and data is exceedingly complex, the range of solutions is broad and the skills market is relatively sparse.

The challenge many experience is that each of these solutions only addresses partial vulnerabilities. Historically we’ve seen customers take the approach of setting up in-house Security Operation Centres (SOC) to implement real-time monitoring and reporting and manage network and information security in an integrated and comprehensive way. However, this has often proven to be expensive and not always effective against the growing threat landscape.

As the focus and intensity on security increases almost daily, many of TNC’s customers are finding that building this level of in-house capability, staying relevant with the security threat landscape, and recruiting and retaining skilled resources who are difficult to find and often very expensive to retain, is often very difficult or even impossible to achieve.

What are the key considerations for customers considering a
Managed Security Service?

One important consideration for organisations is how best to leverage the knowledge of managed service providers whilst retaining an element of control and authority in house. On one hand, customers may be hesitant to consider outsourcing security-related services because of the sensitivity, risk, and potential liability associated with security and data breaches. But many customers also quickly realise that as information security is outside their core competency, the risk of “getting by” internally is far greater.

As a result, TNC’s trend analysis indicates customers have a growing interest in using an established security service capability through an expert third party.

Who offers

Based on TNC’s market insight and access to our customer buying behaviours, we see three main approaches to procuring managed security services

  • Point solutions – use of (multiple) small specialist service providers to deliver niche solutions
  • Managed Security Service Provider – Pure play managed security provider (Dell SecureWorks, Symantec etc.)
  • Telco Service Provider – Specialist business units focussed on managed security (Verizon, BT, AT&T, OBS, CenturyLink, etc.)
