About Material Security

Material Security is the company behind Material, an automated cloud workspace security platform for lean security teams that need to protect the email, files, and accounts that live in Google Workspace and Microsoft 365. Material Security says it secures the productivity suite by stopping attacks and reducing risk across Microsoft 365 and Google Workspace with unified cloud email and file security, data loss prevention and posture management.[2][3][5][7]

Material Security says point solutions and home-grown detections create gaps and drain efficiency. Material replaces that patchwork with a single platform that combines threat detection and response across email, files, and accounts. The company describes modern attacks as deliberately spanning email, identities, data, and connected apps.[3][7][9]

On email, Material remediates sophisticated email attacks that bypass traditional controls. Material automates user report triage with AI-powered investigation and response workflows. Material says it stops VIP impersonations, BEC attacks, and sophisticated phishing that slips past native defenses, including vendor email compromise, invoice fraud, quishing, and ransomware. Material says teams using its automated user report response have cut phishing triage by up to 91 percent at companies like Gusto.[3][5]

On files and accounts, Material detects sensitive content in files and includes tools to automatically remediate excessive permissions and inappropriate sharing. Material detects account takeovers, contains their impact, and hardens accounts. Material monitors signals across the cloud office, from forwarding rules and mailbox rule changes to brute force logins and credential stuffing.[3][7]

Material sells two agents for specific workspace risks. For business-critical clients, customers can require analyst approval before revocation happens. Material's Drive Agent finds and investigates PHI, PII, and sensitive documents shared too broadly in Drive. When over-sharing is identified, the Drive Agent enforces policy and remediates in bulk.[8][9]

On deployment, Material connects to Microsoft 365 and Google Workspace in minutes via native APIs, with no network changes and zero downtime. Material lets customers implement protections for just the users or teams that need them, and syncs groups from Active Directory, Google, or IdPs for targeted deployments and staged rollouts. No agents, plug-ins, or other end-user installs are required. Material can be operated by Material while the customer's team has full access to and ownership of the underlying infrastructure. Material links with SIEM or SOAR platforms to bring cloud workspace visibility and protection under the broader security ecosystem.[3]

On security assurance, Material states it has received a SOC 2 Type II Report through an independent third-party auditor. Material undergoes regular external pentests and runs a private bug bounty program through HackerOne. Material keeps immutable audit logs of all admin activity and application events, and access to the Material admin console can be gated through Single Sign-On.

On pricing, Essentials starts at $4 per user/month, billed annually. Advanced is $6 per user/month, billed annually. ATO Resilience can be added to either plan for an additional $3 per user/month, or bought as a standalone license for $5 per user/month.[14]

Ryan co-founded Material in 2017 and has served as Chairman since 2023. Abhishek co-founded Material in 2017. Chris has been VP of Engineering at Material Security since 2017 and co-founded the company. Material Security says it has raised venture capital from Martin Casado at Andreessen Horowitz, Elad Gil, and Trae Stephens at Founders Fund.[2][3][5][6][7][8][9][10][11][14]
