Most email security tools only look at mail as it arrives; Material Security's differentiator is going backward too — scanning years of historical mailbox content for exposed sensitive data and locking down old messages an attacker could otherwise mine after a breach. Combined with account-takeover detection through behavior monitoring and posture management across Google Workspace and Microsoft 365, it covers more of the actual attack surface than a standard inbound filter.
Pricing is transparent by category standards: Essentials at $4/user/month, Advanced (adds data classification, sharing detection, sensitive-content monitoring) at $6/user/month, both billed annually plus a Shared Drive size fee, with ATO Resilience as a $3/user add-on or $5 standalone. G2 reviewers consistently rate support and ease of administration highly, with few substantive complaints surfacing in reviews — genuinely rare for enterprise security tooling. Best fit: mid-to-large orgs on Google or Microsoft cloud productivity with an existing security team to act on its findings; assumes that team exists.
What people say
Material Security's G2 reviews lean unusually one-sided for enterprise security software — reviewers describe struggling to name a specific dislike, worth noting precisely because it's uncommon; most security tools draw at least some consistent friction complaints (false positives, alert fatigue, a clunky admin UI). Here the recurring theme is the opposite: ease of use, straightforward setup, and administration that doesn't require a dedicated specialist to run day-to-day.
Specific praise clusters around two features. First, real-time remediation and message clustering — when a phishing campaign hits multiple mailboxes, Material automatically groups the related messages so a security team can act on the whole campaign at once instead of triaging one report at a time. Second, the end-user "report suspicious message" flow, which reviewers describe as simple enough that non-technical staff actually use it — a reporting feature nobody uses doesn't generate the detection signal it's built for.
Reviewers comparing Material against category peers (Abnormal AI is a common comparison point) tend to favor Material specifically on support responsiveness and overall vendor relationship, not just product features — easy to overlook when comparing spec sheets but a factor that shows up repeatedly in head-to-head G2 comparison data.
On the business side, Material has raised $162 million total across multiple rounds, with investors including Andreessen Horowitz, Founders Fund, Snowflake Ventures and Elad Gil — a credible enterprise-security cap table, founded in 2017 and based in Redwood City. Pricing is genuinely public, unusual for this category: Essentials at $4/user/month, Advanced at $6/user/month, both annual, plus a Shared Drive size-based fee and an optional Account Takeover Resilience module at $3/user as an add-on or $5 standalone; Enterprise steps up to custom, volume-discounted contracts.
Net: a well-liked, well-funded product with unusually transparent pricing for the category, and review sentiment that's genuinely positive rather than just absent of loud complaints.
