P

Passkey

A passwordless authentication standard that allows users to sign in to apps and websites using biometrics (fingerprint, face scan) or a device PIN instead of a password. Gives MSPs a way to offer phishing-proof authentication. Passkeys work like unlocking your phone, the same fingerprint or face, but now also for logging into apps. No password to forget. No code to intercept. And fake websites simply can't trick it.

Patch Management

The process of applying vendor-issued updates to close security vulnerabilities and optimize the performance of software and devices. The best patch management services detect missing patches, outdated or EOL software, and known CVEs, then correlate that data with risk severity to help teams prioritize remediations.

Phishing

A social engineering attack in which the attacker tries to trick the victim into giving up sensitive information by masquerading as a trusted entity.

PSA

It brings together the service desk and ticketing, time and expense tracking, project management, contracts and SLAs, billing and invoicing, procurement, and reporting in one system, ensuring work is captured, managed, and billed consistently end-to-end.
