About Guardare

Guardare sells a platform that connects data from existing security tools to uncover exposures, prioritize what matters, and give teams clear next steps across people, devices, software, and cloud. Guardare describes its Unified Exposure Management approach as bringing together vulnerability, asset, threat, human-risk, and security-control information. Guardare finds misconfigurations, gaps, and overlaps in the tools its customers currently use. Guardare connects existing tools rather than replacing them, and provides risk scoring and a unified dashboard.[1][4][5][10]

Guardare connects to endpoint, firewall, identity, cloud, and other IT tools through API integrations. Guardare has 200+ integrations that connect existing IT and security tools through read-only APIs, bringing their data into a shared risk context across users, devices, and applications. Guardare integrates with EDRs, XDRs, firewalls, cloud platforms, IAM tools, and SOAR/SIEM systems. GuardScan is an agent that collects Active Directory over LDAP data for on-premises domains.[4][6][7]

Guardare builds a unified risk graph of every user, device, and application, flags critical exposures, and ranks them by business impact. Guardare combines classical machine learning and large language models with human oversight. Guardare predicts how each organization could be targeted based on its tech stack, policies, and procedures.[6]

Guardare was developed in-house with purpose-built AI. Guardare trained its AI on datasets like MITRE and other CVE sources, then expanded it with insights aligned to frameworks such as NIST, ISO 27001, CMMC, and CIS Controls. Guardare draws from data sources such as MITRE ATT&CK and global CVE databases.[6]

Guardare gives natural language instructions in order of importance to help lower risk. Guardare translates technical findings into plain-language reports with clear recommendations. Guardare lets teams assign recommendations to people, create Jira tickets, and track recommendation status. Paul Whiteside is the subject of a Guardare case study about a security stack spread across nine tools.[4][6][8]

Guardare pricing is based on employees with a digital footprint, such as a work email address. Guardare customers are billed annually in advance under their selected 1-year or 3-year contract term. Customers can purchase Guardare directly from the company or through a partner. Guardare shows separate SLED and nonprofit rates. Guardare provides connected exposure visibility across people, devices, software, identity, and cloud. Guardare provides risk-based prioritization to help teams decide what to address first. Guardare provides reporting to help explain findings and progress.[9]

Guardare offers Support Services 24 hours per day, 7 days per week for Severity Level 1 incidents, via phone and online ticket submission. Guardare uses commercially reasonable efforts to meet a monthly Target Availability of 99.9% for its Subscription Services. Guardare states it will maintain security controls for its Subscription Services, including encryption of data in transit with TLS 1.2 or higher and at rest.[10]

Guardare says it provides organizations with tools for SMB risk management and risk prioritization.[4][6][10][11]
