The contracts have a combined revenue value in excess of £750,000. The revenue will be recognised throughout the duration of the contracts, which vary between one and three years.
The largest contract is to provide “always-on” cyber-security monitoring and breach detection, using ECSC’s proprietary Kepler Artificial Intelligence.
The contract win came in the wake of ECSC's response to a major security incident within a chemical company.
Three of the other four contracts also use the Kepler Artificial Intelligence technology; one is a two-year renewal from a well-known retailer; another is a new three-year contract with an information technology services company and the third is a one-year contract extension with a financial services firm.
The fifth contract is a cyber-security testing programme for a new client providing mobile payment solutions.
"We are pleased to end the year on such a positive note with a number of major contract wins across a range of sectors,” said Ian Mann, the chief executive officer of ECSC.
“Following the new 2019 GDPR [general data protection regulation] fines, clients are increasingly recognising the need for cyber-security services. Our strategy of winning consultancy clients, and developing them into long-term recurring managed services clients continues to be effective," he added.
Shares in ESCS were up 8% at 135p in early deals.
