Business Features
Cloud Email Gateway
Email Systems: seamless integration with Microsoft 365, Exchange, Google Workspace without additional hardware or software
TLS Connection: connection of customer systems via opportunistic or enforced TLS (Transport Layer Security)
VPN Connection: connection of customer systems via VPN (Virtual Private Network)
User-Based Routing: delivers emails for specified recipients within a domain to specific target servers/configurable MTAs
Predelivery Logic: additional and comprehensive routing capabilities using customizable rulesets
Directory Synchronization (DirSync): reconciliation of address books and directory services from Microsoft (Exchange, Active Directory, Azure Active Directory (AAD) for Microsoft 365), HCL Notes Domino and LDAP (Directory Synchronization)
Directory Filter (DirFilter): rejects incorrectly addressed (i.e. attempted denial of service and directory harvesting attacks) emails in accordance with RFC and/or handles them with traffic throttling mechanisms
Inbound Reputation Management (SPF, DKIM, DMARC): supplements the Directory Filter checking the reputation of the senders (Email Authentication) using SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail) and DMARC (Domain-based Message Authentication, Reporting and Conformance)
myEAS: admin portal with granular, hierarchical access rights management for administrators
Monitoring and Reporting: easy management of service instances and user profiles via Retarus myEAS, including detailed (custom) report, analysis functions and real-time performance monitoring
Email Live Search: ability to track how a message was processed via search filters over a period of 45 days with near instantaneous results
Multi Data Center Connection: high availability and disaster recovery through globally distributed Retarus data centers
Scalability: cloud service designed to process high email volumes
Compliance: meeting data processing regulations through local data processing in Retarus data centers
24/7 support: operated directly from Retarus with no third-party outsourcing
Email Security
Available Packages: Essential Protection (EP: AS, AV, Phishing); Advanced Threat Protection (ATP); Post Delivery Protection (PDP); Sandboxing; Forensic SIEM
Quarantine Management (via email and browser): simplified email handling for employees and administrators. At customizable points in time, reports sent by email (Email Digests) and Online Quarantine web portal offer a quick view of emails flagged for deletion or quarantine.
AntiSpam Management: runs spam checks of incoming emails using rules and tools (e.g. content and structure analyses/heuristic methods, "bad word" filter, fingerprint analysis, Machine Learning, sender check); continuous updates of intelligent filter, pattern, and identification rules: backscatter protection; multi-lingual content analysis
AntiVirus MultiScan (up to 4x): scans incoming and outgoing messages as well as file attachments for viruses using heuristic analysis (Zero-Hour Protection)and continuous updated virus definitions of various market-leading sources
Phishing Filter: detects phishing emails that are not yet caught by the AntiVirus MulitScan or AntiSpam Management using query of several databases of renowned specialized providers (see also Time-of-Click Protection)
Forensic SIEM Integration: provisioning of real-time forensic data in the form of events via protected interface to exisiting SIEM tools
Sandboxing: subjects file attachments to an in-depth analysis (e.g. files and active elements) in a virtual machine checking for unusual behavior using a combination of static and dynamic analysis as well as machine-learning algorithms
Attachment Blocker: blocks selected attachments from reaching the company infrastructure eg. .exe, .zip, or Office files with macros.
CxO Fraud Detection: uses algorithms that identify from-spoofing and domain-spoofing, to detect falsified senders (i.e. "impersonation attacks", "Business Email Compromise (BEC)"), based on combination of detection methods and algorithms (header analysis, domain similarity, recognition of fake sender names)
Deferred Delivery Scan (DDS): effective re-scanning with quadruple Retarus AntiVirus MultiScan protecting from viruses that were unknown at time of initial scan
Time-of-Click Protection: automatically re-writes URLs in emails offering continuous protection against suspected phishing target addresses through real-time checks, effective blocking of websites and customized warnings for affected users
Patient Zero Detection®: patented solution using digital fingerprints to identify emails containing malware or phishing links that have already been delivered to the user's inbox (Post delivery protection)
Patient Zero Detection® Real-Time Response: allows results to be processed in a rule-based manner and automatically move or delete potentially dangerous emails from a user's mailbox
