We are dedicated to helping small companies stay protected from cyber attacks and data loss.

At SEIRIM we are philosophically driven in regards to cybersecurity. We have a strong disdain for malicious actors and their selfish attacks on society.

We know it sounds hyperbolic, but it's true, and it is what drives us to help companies safeguard their operations and data. Our goal is to help companies defend their information and communications as strongly as possible.

We believe that every company has the right to achieve a level of security whereby all the IT systems they rely on are safe from being undermined.

Delivering affordable professional cybersecurity services for SME’s.

As a small company ourselves, we are focused on helping bring affordable cybersecurity to all sizes of companies and budgets. There is too large a gap in accessble cybersecurity services for small and medium sized companies, while at the same time attacks on them are increasing.

In this environment, we are dedicated to delivering affordable, transparent cybersecurity consulting and services - at the right level for any company. We are available from small consultations or batches of service to more full-time engagements to help complement a company's internal security framework.
