About Us

Saporo’s mission is to help organizations increase their cyber resistance no matter their size or industry. Thanks to a unique approach and cutting-edge technologies, we aim at making defenders win the race against attackers and put order in chaos.

The problem we saw

Privileged account access represents the keys to the kingdom for threat actors, enabling them to move around a network almost unabated. With it, attackers can explore and extract as much sensitive data as they like. These same privileged accounts then allow the threat actor to encrypt that same stolen data and hold the organization at ransom. Identifying all potential attack paths in large and dynamic environments is impossible using manual methods. Finding, quantifying and prioritizing where to start and what to do requires automation.

How we solved it

Defenders can never hope to get ahead of attackers if attackers have a better understanding of the battlefield - the organizations own network. By leveraging the same techniques used by threat actors to visualize the most critical paths to critical resources, defenders can start to see their environment as attackers do. Once visibility is achieved, it becomes much easier to anticipate attack paths and implement the appropriate countermeasures and controls.

Time is of the essence.

It is a race of time between the attacker and the defender. Winning the race against attackers requires ordering the seemingly chaotic connections between users, assets and resources to expose and prioritize paths that attackers will most likely exploit.
