Email security controls protect against phishing, business email compromise (BEC), malware delivery, and spam — filtering inbound threats before they reach users, preventing impersonation attacks through authentication enforcement, and detecting account compromise through behavioral analysis.
Email remains the #1 initial access vector in enterprise breaches. Phishing campaigns are increasingly sophisticated — bypassing legacy email gateways with AI-generated content and evasion techniques. Modern email security requires layered controls that go beyond standard spam filtering.
A structured advisory process — from security posture assessment and market evaluation to vendor selection, contract negotiation, and post-deployment validation — tailored to your risk profile and compliance obligations.
We evaluate your existing email security posture — inbound filtering effectiveness, authentication record configuration (SPF, DKIM, DMARC), impersonation protection, and the phishing simulation results that quantify your human risk.
We evaluate email security platforms — Proofpoint, Mimecast, Abnormal Security, Microsoft Defender for Office 365, and cloud-native email security — against your threat profile, M365/Google Workspace environment, and the advanced threat capabilities your risk profile requires.
SPF, DKIM, and DMARC prevent domain spoofing and provide the authentication foundation for email security. We assess your current authentication posture and design the enforcement path to DMARC reject policy.
Technology controls reduce phishing success rates; security awareness training reduces click rates. We design the integration between email security controls and your phishing simulation and training program.
These are the dimensions that consistently separate effective security programs from expensive ones — and the questions RLM will help you answer before any vendor commitment.
Business Email Compromise — impersonation of executives and vendors requesting wire transfers — causes significant financial losses. Evaluate the platform's BEC detection capability specifically, including lookalike domain detection and display name spoofing.
Attackers increasingly use AI to generate phishing content that bypasses URL filtering and content analysis. Evaluate the platform's behavioral analysis and anomaly detection capabilities that catch novel phishing that signature-based controls miss.
Compromised email accounts send phishing from trusted domains that bypass inbound filtering. Evaluate behavioral analysis capabilities that detect account compromise through anomalous sending patterns, login anomalies, and rule changes.
Native email security integrations with M365 and Google Workspace provide deeper API access than MX-record-based gateways. Evaluate whether API-based integration provides better detection for your specific environment.
Phishing URLs that are clean at delivery become malicious after delivery (delayed weaponization). Evaluate time-of-click URL analysis that checks URL reputation when a user actually clicks — not just at delivery time.
Email security quarantines generate end-user friction and helpdesk volume. Evaluate the quarantine workflow — user self-service release, false positive rates, and the helpdesk burden — before selecting a platform.
"RLM helped us build a security program that satisfied our board and our auditors — without locking us into a single vendor's roadmap. Their independence is the whole point."
"We had three overlapping security tools doing the same job. RLM helped us rationalize the stack, cut spend by 30%, and actually improve our detection coverage in the process."
Start with a no-cost conversation with an RLM security advisor — vendor neutral, no agenda, just clarity on where your gaps are and the right path to close them.
