ePIN provides state-of-the-art security and system availability to ensure that your operations are never compromised. With ePIN you enjoy the protection and peace of mind that only our world-class security infrastructure can provide.


ePIN’s primary systems are hosted by our long time partners Rackspace. Located in a blast-proof building with 24 hour on-site security and monitoring, the facility is at the heart of the UK's Internet connectivity with direct connections to major UK, transatlantic and European ‘backbones’. Power to the site is maintained by multiple feeds backed up by long-range on-site emergency generators.


ePIN aims to achieve a target availability of 99.999%. To achieve this, ePIN deploys highly available redundant systems at its primary site, which are mirrored at a secondary disaster recovery location. We utilise a hybrid-cloud model, enabling the rapid addition of additional capacity for best in industry performance, whilst maintaining our client's data on dedicated private infrastructure. Our applications are designed to run on single servers or distributed across standard ‘n-tier’ architectures, thus providing maximum flexibility in disaster recovery situations. Standard best practice resilience measures are adopted such as: load balancing, clustering, mirrored SCSI disk arrays with hardware RAID, hot-swap drives, power supplies, and cooling fans. Bandwidth demand is also monitored to ensure that systems capacity always comfortably exceeds demand.

Backup tapes are taken daily, weekly and monthly and stored off site with redundant overlap. In the event of transportation difficulties or more serious emergencies, our support staff can manage our systems from home.

In the last 12 months, unscheduled downtime of ePIN's systems has been less than 1 minute, comfortably exceeding our target availability.

System security

ePIN constantly assesses its own security against current best practice and current threats, generally adopting the requirements and guidance of the US Government National Security Agency which covers all aspects of system and organisational security. ePIN applies a multi-layered design philosophy to its network security, always assuming that other measures in front of any particular location may have been breached. Individual components of the system are hardened to withstand direct attack, ensuring we never rely on just firewalls for protection.

First-line security consists of twin redundant routers acting as packet filters. This coarse but efficient screening of traffic allows very best performance from the second layer security appliances that sit in front of load-balanced web servers. In a typical n-tier topology, load-balanced authentication servers and clustered database servers operate on separate networks, again protected by industry leading security appliances.

Application Security

Unlike other providers, ePIN adopts separate databases and data stores for each client, ensuring maximum security and integrity of data. Security is applied both at the operating system and database levels, and all user logon and authentication interactions are encrypted.

By providing a fully-managed service, ePIN helps minimise security threats caused by poor administration practices. By relieving its clients of the added burden of systems administration, ePIN not only reduces the cost of operation, but also ensures that administrative problems such as changes in personnel, do not unwittingly give rise to security threats. In so doing, ePIN allows its clients to concentrate on their core business rather than systems administration.


Good performance generally goes hand in hand with distributed and resilient systems. But application design is also vitally important, and ePIN is well known for the snappy performance and availability of its systems.
