Armorblox helps organizations communicate more securely over email. Armorblox has developed a Natural Language Understanding (NLU) platform that protects businesses against targeted email attacks and data loss. Armorblox connects to email providers–Microsoft 365, Google Workspace, and Exchange–over APIs and uses machine learning to analyze thousands of signals to understand the context of communications. Using this context, Armorblox: - Stops advanced email attacks like Business Email Compromise (BEC), payroll fraud, financial fraud, spear phishing, and other threats that evade traditional email security controls. - Protects sensitive PII, PCI, and unencrypted passwords from being shared with unauthorized recipients over email. - Automates triage and remediation of user-reported email threats, freeing up security teams to tackle other proactive cybersecurity concerns. - Provides Data Loss Prevention (DLP), preventing accidental or malicious exposure of data. With Armorblox, Security teams are able to automate away up to 97% of their manual work associated with user-reported phishing emails, freeing up their time to focus on more proactive security measures. After using Armorblox, user-reported email threats are reduced by 60-85% because Armorblox has already detected and dealt with the threats. Armorblox protects over 58,000 organizations from targeted email attacks. We analyze over 2.5 billion emails a month and stop over 500,000 threats every month. Armorblox was featured in the 2019 Forbes AI 50 list, the Gartner 2021 Market Guide for Email Security, and the Gartner 2022 Market Guide for Data Loss Prevention. Founded in 2017, Armorblox is headquartered in Sunnyvale, CA and backed by General Catalyst and Next47.
