Retarus —
Cloud Fax, Enterprise SMS, Transactional Email & Email Security

Retarus fits enterprise and mid-market operating models — particularly healthcare, financial-services, manufacturing, logistics and other regulated verticals — whose business-messaging posture spans cloud fax, enterprise SMS, transactional email and email security under one provider rather than across separate fax, SMS, email-delivery and email-security vendors. Operating models with global footprint, multi-region delivery requirements and compliance constraints (HIPAA, SOC 1 / SOC 2, PCI-DSS, GDPR) are the natural fit.

Retarus delivers Cloud Fax (managed faxing across faxolution-style integration patterns), Enterprise SMS (high-volume transactional and notification SMS), Transactional Email (high-deliverability email APIs and SMTP relay), Email Security (advanced threat protection, anti-phishing, encryption and patient-communication scenarios) and Business Integration messaging — under one enterprise messaging platform rather than across separate point vendors.

Generic transactional-email vendors cover email delivery but not fax, SMS or email-security posture. Generic CPaaS / SMS providers cover SMS but not fax, transactional email or email security. Email-security pure-plays cover threat protection but not the underlying delivery infrastructure for transactional email and SMS. Retarus combines cloud fax, enterprise SMS, transactional email and email security under one provider — fitting operating models whose business-messaging posture cannot be fragmented across multiple SaaS vendors with different SLAs and compliance scopes.

Retarus operates a global messaging platform with multi-region delivery, redundancy and audited compliance posture (SOC 1, SOC 2, HIPAA, PCI-DSS, GDPR alignment) — fitting healthcare, financial-services and regulated operating models whose patient-communication, transaction-notification and document-delivery scope cannot tolerate single-region SaaS or best-effort delivery. The platform is engineered for transactional / business-critical messaging rather than marketing-grade volume.

Operating models running separate email security (anti-phishing, ATP, encryption) plus separate transactional-email plus separate fax plus separate enterprise SMS often consolidate onto Retarus to reduce vendor count and align SLAs. Operating models with strong existing relationships in one of those scopes (e.g., Microsoft Defender for Office 365 already in place) can deploy Retarus selectively where it overlaps least and adds most — typically cloud fax, enterprise SMS and transactional email first.

No. Your service agreement is signed directly with Retarus and Retarus's standard enterprise terms apply. Fibi's role is to scope your fax / SMS / transactional-email / email-security objective against Retarus and the most relevant alternatives — including separate transactional-email vendors, separate CPaaS providers, and separate email-security providers — so you see how Retarus's combined-platform posture compares before signing. Fibi's advisory work is provider-funded.
