About Guardz

Guardz sells an MSP-ready security platform that brings identity, endpoint, email, data, awareness, and exposure protection together. Guardz says attackers move across identities, email, endpoints, web, and data. Guardz connects the entire workspace through a unified data fabric, enabling autonomous detection, investigation, prioritization, and response. Guardz describes one data fabric with three layers, including intelligence that learns and agents that triage and respond. Guardz says it automatically correlates signals across customer environments so a team can see what matters, act faster, and show the value behind each action.[1][2]

Identity Threat Detection & Response (ITDR) verifies MFA and security settings, and benchmarks and analyzes user behavior to flag suspicious activity. ITDR monitors identity behavior across the cloud to detect unusual activity, correlate risk signals and trigger targeted responses. Guardz natively integrates with M365 and GWS to run analysis across the most critical cloud logs without complex integrations or service accounts. Guardz lets teams suspend compromised accounts and isolate users in a single action to contain attacks before they spread.[2]

Guardz offers AI-native EDR with SentinelOne embedded and Managed AV with Windows Defender, which Guardz says ensure real-time protection across devices. SentinelOne provides the endpoint engine, and Guardz makes it operational across clients. Managed AV supports Windows and Macs, while SentinelOne EDR supports Windows, Mac and Linux. Kill, Quarantine, Remediate, Roll-Back and Isolate Device can be automated, triggered by the MSP or executed by the MDR team. SentinelOne licenses are included in the Ultimate Plan, and alerts are managed by the Guardz MDR team. Guardz agents can be deployed through RMM and MDM flows with minimal end-user involvement. Alerts from Guardz can be sent through email and syslog into existing workflows.[2]

AI runs response playbooks at machine speed to contain threats and automate remediation, with 24/7 MDR experts handling cases that need human investigation and action. MDR adds human investigation and response around the clock.

Guardz email protection uses an API-based and AI-native engine to prevent credential theft, ransomware, and impersonation threats in real time. Check Point Harmony powers Guardz Email Security, stopping email threats with connected security operations for MSPs across clients. Cloud Data Protection works by analyzing user activity and behavior within cloud applications to identify and prevent threats. Guardz scans the settings, security configurations, user activity logs and token grants of cloud applications through public APIs.[2]

Guardz offers web security through a browser extension that escalates risk around employees exposed to malicious sites, web redirects, and unsafe extensions. Prisma Browser for Business uses the context of the active browsing session to detect and block threats as users encounter them. Guardz connects browser blocks and policy events with identity, email, and endpoint activity. Guardz scans for open ports and public exposures to prevent malicious actors from accessing vulnerable and outdated services. Guardz continuously monitors the internet for leaked credentials and exfiltrated data.

Guardz offers pre-scheduled security awareness training that alters behavior and limits human-driven cyber risks before they escalate. Guardz helps teams plan, launch and track automated training campaigns that boost employee vigilance and shut down human-driven risks. Campaign frequency can be set monthly, bi-monthly, or quarterly. Guardz Phishing Simulation empowers MSPs to run lifelike, AI-generated attacks tailored by tone, industry, and language. Training videos and phishing simulations are available in more than 70 languages. Failed simulations trigger an awareness issue, and admins can assign instant training.[2][14][15]

Guardz builds its platform for MSPs. Guardz lets MSPs centrally navigate the security of multiple clients, either aggregated or in their unique individual environments. MSPs can set global configurations once and push them across every client, with automated detection and remediation working continuously in the background. Prospecting Reports scan a client's public-facing assets to uncover security gaps. Evidence mapping reports how Guardz security controls align with frameworks like SOC 2, ISO 27001, HIPAA, and GDPR. Guardz client reports are delivered monthly, quarterly, or on-demand and highlight threats, risk, and mitigation activity.[1][3][16]
