Cellopoint

What Cellopoint does

Cellopoint International Corporation, headquartered in New Taipei City, Taiwan, is a privately held email security and email lifecycle management (ELM) vendor founded in 2003 and operating for 20+ years with a global channel footprint and 3,500+ reported customers. Its portfolio covers inbound threat protection (Cellopoint Defender for Microsoft 365 as an Integrated Cloud Email Security solution, Secure Email Gateway, Cellopoint Online Protection), outbound data protection (DLP, CODLP, Digital Signature, Encryption), and email archiving (Mail Archiving, Online Archiving, Grid Search, Case Management), all powered by the proprietary CelloOS 4.8.0 platform, CelloCloud, and the CelloAI engine that performs NLP, behavioral analysis, OCR-based DLP, and ML-based BEC detection across trillions of analyzed messages.

The company monetizes primarily through subscription and SaaS models — monthly billing for COP/CODLP/Defender, annual maintenance for SEG module licensing, and hardware appliances for on-premises deployments — with quote-based, non-public pricing. Go-to-market is channel-led through Platinum/Gold/Silver reseller tiers, MSP and regional distributor programs (Stark Technology Inc., TerraONE, uniXecure), and technology partnerships with Microsoft, Google, Bitdefender, Trellix, and Opswat. Customer segments include large enterprises, Microsoft 365 users needing augmentation beyond native EOP, on-premises Exchange/Zimbra estates, SMBs, government agencies, and MSPs. Cellopoint holds ISO 27001:2022, 27017, and 27018 certifications and has been recognized in three Gartner reports, including as the only APAC representative Integrated Cloud Email Security vendor in the 2023 Gartner Market Guide. Recent activity (2024-2026) has centered on CelloOS platform releases, a deliberate Southeast Asia expansion into Vietnam/Thailand/Malaysia, and partner enablement through CCSE technical certification programs.

Direct peers

• Proofpoint: Proofpoint is the largest independent email security vendor, offering Threat Protection, DLP, archiving, and adaptive controls. Directly comparable on SEG, ICES (Microsoft 365 augmentation), email DLP, and archiving, with significant overlap on the enterprise buyer profile Cellopoint targets.
• Mimecast: Mimecast provides cloud-native email security (anti-phishing, BEC, ransomware), DLP, and archiving via its Mime|Main integrated platform. Closely aligned with Cellopoint across SEG-style deployment, M365 augmentation, and email archiving — the most direct product-for-product competitor.
• Barracuda Networks: Barracuda offers Email Protection (gateway + API-based), archiving, DLP, and phishing/BEC defense across both on-premises and SaaS deployment. Closely comparable product set to Cellopoint's SEG, Defender, DLP and archiving lines, with stronger SMB and mid-market channel reach.

Emerging players

• Abnormal Security: Abnormal Security is an AI-native email security platform focused on BEC, account takeover, and social-engineering attacks via API integration with M365/Google Workspace. Mirrors Cellopoint's CelloAI API-enabled approach and is one of the highest-profile AI-native challengers in the same Microsoft-graph deployment model.
• Cofense: Cofense (formerly PhishMe) focuses on phishing defense and reporting, combining crowdsourced threat intelligence with email security. Comparable to Cellopoint on the anti-phishing / threat-intelligence side of the portfolio, particularly around BEC and credential-phishing protection.
• Cloudflare Email Security (Area 1): Cloudflare's Email Security (acquired from Area 1 Security) is an API-based anti-phishing platform integrated with M365 and Google Workspace. Directly competes with Cellopoint Defender on AI-driven phishing/BEC detection, but with materially larger engineering and channel resources via Cloudflare's network.
• Cloudflare Area 1 / Vade Secure: Vade Secure (now operating under Hornetsecurity post the 2024 acquisition) is a European-headquartered AI-driven email security vendor with comparable ICES + SEG positioning. Relevant comparable because it shares Cellopoint's mid-market-oriented pricing and channel focus, with stronger European channel presence.

Broad incumbents

• Microsoft Defender for Office 365: Microsoft Defender for Office 365 is the native email-security stack bundled into Microsoft 365 / EOP. It is both the ecosystem Cellopoint integrates with and the principal competitive incumbent; its expanding native capabilities define the gap Cellopoint's augmentation products are selling against.
• Sophos Email: Sophos offers email security (anti-phishing, anti-BEC, DLP) as part of its broader cybersecurity portfolio (endpoint, firewall, MDR). Overlapping capability with Cellopoint's SEG and Defender products, but sold by Sophos as part of a wider platform rather than as a focused email-security franchise.
• Trend Micro Email Security: Trend Micro (now part of the APAC heritage ecosystem alongside Cellopoint) provides email security as part of its broader cybersecurity suite, including anti-phishing, anti-BEC, and DLP. Comparable functionality to Cellopoint's SEG and Defender lines, but positioned as part of Trend's wider XDR platform.
