The third-party access problem
Almost every organization grants outsiders privileged access: the ERP consultant tuning the database, the HVAC contractor maintaining building systems, the software vendor troubleshooting their product on your servers, the managed service provider running your network. Traditional plumbing for this is a VPN account plus a shared password — which places an unmanaged laptop, secured to someone else’s standards, directly inside the network.
Vendor privileged access management replaces that pattern with brokered access. The vendor authenticates through a portal with their own identity and MFA, is connected only to the specific systems in scope, for an approved time window, with credentials injected by the platform rather than disclosed. Several high-profile breaches began with stolen vendor credentials, which is why this niche earned its own acronym.
Why VPN-based vendor access fails
A VPN is network-level access: once connected, the vendor can typically reach far more than the one system they came for, and their onward activity is invisible beyond flow logs. Vendor VPN accounts also rot — engagements end, technicians change employers, and the credentials stay active because nobody inside the customer organization owns the offboarding.
Accountability compounds the problem. Vendors often share one login among a team, so the customer cannot tell which technician connected, and contractual or regulatory duties — proving who accessed patient data, production controls or cardholder systems — become impossible to meet. Frameworks like NIS2 and ISO 27001 explicitly extend supply-chain and access-control requirements to third parties, making unmonitored vendor VPNs an audit finding waiting to happen.
VPAM in practice
A VPAM rollout starts with an inventory of third parties holding access, then moves them from VPN accounts to a brokered portal. Each vendor technician gets an individual identity; access is requested per engagement, approved by the internal system owner, limited to named targets and an expiry date, and every session is recorded. When the engagement ends, access lapses automatically instead of lingering.
Browser-based gateways make this practical because vendors need no client software or network membership — just a URL and their credentials. Monopam supports vendor scenarios with agentless browser-based RDP and SSH, JIT approval workflows, credential injection from the vault and full video and keystroke session recording.
