Pasi Korhonen

Pasi’s career started with updating information systems for the turn of the millennium. He moved into consulting after specializing in implementations of the Data Protection Directive.

Pasi has worked as a senior consultant in security and IT risk management for 20 years. He believes there’s no one-size-fits-all model in cyber security and cyber resilience. Clients may face similar problems, but solutions are always unique.

The key is to know your operating environment – technology, processes and people. First, you must understand your current state; only then can you protect yourself.

Pasi enjoys conducting training sessions and frequently presents to parliamentary committees, where complex issues must be simplified. His latest research projects focus on AI auditing and trustworthiness.

Antti Laatikainen

Antti became interested in cyber security while working in the healthcare industry as a network administrator, and realized that security of corporate IT systems could be circumvented just as easily as in the games he played.

After building security posture and practices for his then-employer, Antti became a consultant and now travels the world helping clients protect their customers, employees and organizations from attack.

Antti specializes in security- and risk management, current state analysis and compliance programs; cases where technical security needs to be accompanied by human processes, understanding of larger threat landscapes and business objectives.

Antti frequently engages in public speaking and training sessions, educating large audiences about cyber security, risk awareness, and compliance.

Mohit Gupta

As an undergraduate studying electronics and AI, one of Mohit’s friends showed him how to bypass a login with an SQL injection – and set him on course for a career in cyber security.

An internship here in his second year led to a job on graduation and the freedom to explore multiple areas of cyber security since 2016.

Mohit helped develop our expertise in cloud security practices, but has also spent serious time tinkering with Kubernetes, developing in-house tools and investigating network security, OSINT and product security.

His favorite project? Bypassing fingerprint readers with ‘less than £50 worth of stuff from Amazon’.
