Traditional access control systems were designed for employees on managed devices, but today's blended workforces force administrators to manage a shifting mix of employees and contractors who could be anywhere in the world. Securing contractor access is a particular concern for DevOps teams due to supply chain attacks that are accelerating and making developers primary targets for credential theft. Legacy VPN technologies make this situation worse by giving contractors access to any resource and service on the network, similar to how hackers compromise an IT supply chain. A modern approach of Zero Trust Network Access (ZTNA) offers a path to better access and better security by providing granular control over resource access through the principle of least privilege. ZTNA systems decouple access control from the physical network, making managing contractors much easier, and eliminate lateral movement techniques that hackers use to expand their foothold in networks. By adopting ZTNA solutions like Twingate, companies can protect their codebase from direct attack, reduce supply chain risk, and improve contractor experience without the headaches of VPN.
