78% of security teams are overwhelmed with the volume of alerts they receive. Analysts are stretched, leading to fatigue and talent-attrition. The number of unfilled cyber security jobs will reach 3.5 million by 2021. We believe that a great answer to these and other challenges facing today's security teams is advanced security automation. By automating repetitive workloads, security teams can refocus their resources on higher-impact activities aimed at reducing their organisation's risk posture. We built Tines because we wanted an easy-to-use platform that would allow security teams automate any workflow, regardless of complexity, without having to fallback on bespoke scripting that's hard to maintain, manage and scale.
