Shielding $90B in Capital Under Management from Cyber Threats

Challenge

One of the largest direct lenders in the US, Antares Capital serves hundreds of PE-backed companies. Here, lateral movement isn’t just a security risk – it’s a portfolio risk. While locking down lateral movement across their network was a cross-functional priority for Antares, decades of accumulated complexity stood in the way.  

Disparate legacy assets made it difficult for Antares to get a complete view of the network, so the team struggled to identify which ports where necessary for business operations, and legacy segmentation required too much manual effort to be a viable solution. 

Solution

Antares turned to Zero Networks to granularly segment their network using native controls. Zero’s agentless, automated solution delivered comprehensive protection without degrading performance or requiring dedicated resources. 

Zero’s automated learning capability discovered all network assets and identities – including legacy systems – and automatically learned network traffic patterns, using this baseline to generate deterministic, highly accurate rules and policies that Antares could effortlessly apply at the host level. And with Zero’s robust automation engine dynamically adapting policies as the network evolves, Antares future-proofed its security posture.  

Result

With Zero Networks, Antares implemented microsegmentation across their network in less than three months without adding operational complexity or degrading performance. Thanks to Zero’s automated approach, Antares freed up a collective 10+ hours of work each week across multiple teams.  

With every asset isolated inside its own secure zone, Antares ensured that even if attackers manage to gain initial access to the network, they can’t move laterally to escalate privileges – so critical systems and services keep running, even during a breach.
