- Proofpoint products are designed to solve three business problems: advanced cybersecurity threats, regulatory compliance, and brand-impostor fraud (which it calls "digital risk"). These products work across email, social media, mobile devices, and the cloud - Email security In June 2008, Proofpoint acquired Fortiva, Inc., a provider of on-demand email archiving software for legal discovery, regulatory compliance and email storage management. Fortiva used Exchange journaling to automatically archive all internal and external communications so that end users can search all archived messages, including attachments, directly from a search folder in Outlook.

- Cybersecurity Proofpoint's security portfolio includes products that stop both traditional cyberattacks (delivered via malicious attachments and URLs) and socially engineered attacks - such as business email compromise (BEC) and credential phishing that do not use malware. It uses a blend of sandbox analysis, reputational analysis, automated threat data, human threat intelligence and attributes such as sender / recipient relationship, headers, and content, and more to detect potential threats. Automated encryption, data-loss prevention and forensics-gathering tools are designed to speed incident response and mitigate the damage and costs of any threats that do get through. The portfolio also includes protection from social-media account takeovers, harmful mobile apps, and rogue Wi-Fi networks.

- Regulatory compliances Proofpoint's compliance products are designed to reduce the manual labor involved in identifying potentially sensitive data, managing and supervising it in compliance with government and industry rules, and producing it quickly in e-discovery legal requests.

- Digital risk digital risk products are aimed at companies seeking to stop cybercriminals from impersonating their brand to harm customers, partners, and the brand's reputation. Its email digital risk portfolio includes authentication technology to prevent email domain spoofing. On social media, it stops scams in which fraudsters create fake customer-service accounts to find people seeking help over social media and trick them into handing over account credentials or visiting a malicious website. And in mobile, it finds counterfeit apps distributed through mobile app stores.
