About Reach Security

Reach Security is an AI-native security company focused on giving customers a single interface to understand and operate security controls at scale. Reach delivers a platform that uncovers misconfigurations, control weaknesses, and other exposures, then drives prioritized, guided remediation at scale. Reach is an exposure management platform designed to identify and close configuration gaps in security tools before AI-powered attacks can exploit them. Reach is an AI-Native Security Controls Operating System that integrates with an existing security product stack to reveal and remediate defensive blind spots, and activate underutilized capabilities across the security control plane.[1][3][4][5][11]

Reach uncovers misconfigured, incomplete, and underused controls across existing identity, endpoint security, SASE, network security, and other deployments. Reach prioritizes action to close defensive gaps based on the severity of exposure, attack behaviors, and configuration context. Reach automatically pushes recommended configuration changes into a staged environment for verification, then executes tailored remediation workflows across the security ecosystem via integrations with ticketing systems. Reach continuously monitors configurations to detect drift and validates that controls are working as intended. Reach uses cybersecurity domain-specific AI models to surface and prioritize reachable risks.[4]

Reach integrates with the security stack already owned across identity, endpoint, email, and network security. Reach connects with existing security technology stacks using read-only APIs to give operational visibility across every security control. Reach identifies and prioritizes exposure risks across email, network, endpoint, SaaS applications, and identity access management. Reach provides visibility into defensive weaknesses like misconfigured security controls, configuration drift, unused security capabilities, and vulnerabilities across the entire IT and security stack. Reach automates remediation with context-driven recommendations, deployment guides, and change tickets tailored to tools and environment.[4][6][7]

Reach continuously monitors security control configurations across IAM, EDR, email security, firewalls, SASE, and more, and alerts teams to changes that affect security posture. Reach keeps a full audit trail, prioritizes fixes, and provides guided remediation of drift events. Reach shows what changed, where and how it happened, and the impact. Reach analyzes the environment to identify unpatched vulnerabilities that are still reachable and then recommends and applies compensating controls across the existing stack. Reach connects directly to existing security tools to provide a consolidated view of how defenses are configured across people, assets, and systems. Reach identifies misconfigurations and underutilized capabilities across a Microsoft security stack, then deploys fixes to optimize tooling and eliminate exposures. Reach continuously evaluates E3/E5/E7 environments to identify gaps and improvement opportunities.[4][5][7][8][9]

Insurity automates analysis across its ZTNA tools with Reach and uncovered risky access and misconfigurations. Reach has been integrated in the Autodesk environment. Reach is not a Security Incident Event Management (SIEM) product. Reach handles data in three categories: identity service data, security event logs, and security product configurations. Data retention is set to 15 months by default for all security event and identity data processed by Reach. Reach AI relies on verified, domain-specific data to power its configuration engine, with third-party LLMs kept out of the mix. Reach encrypts data at rest using AES-256 encryption.[10][11]

Reach Security announced a Series B round of more than $50M. Reach Security makes staff available for Application Administration between 9:00 am and 5:00 pm Pacific Time, Monday through Friday.[1][2][3][5][12]
