Email Security ServicesBeyond Microsoft 365.
DMARC. BEC Detection. Advanced Filtering.

Over 90% of successful cyberattacks begin with an email. Microsoft 365 includes basic email filtering — but it was not designed to stop sophisticated phishing, BEC impersonation, or domain spoofing. Attackers specifically study and evade Microsoft's default filters. A phishing campaign that gets past Microsoft's EOP lands in your employees' inboxes with no warning. A BEC attack that impersonates your CEO or a trusted vendor doesn't trigger Microsoft's rules because it doesn't contain malware — it contains a convincing request. Gradius delivers layered email security services for NJ, NY & CT businesses — advanced filtering beyond M365 defaults, DMARC/DKIM/SPF authentication, BEC and impersonation detection, anti-phishing with link sandboxing, and continuous email security management.

The Email Security Stack

Every Layer of Email Security Your NJ, NY & CT
Business Needs — Beyond What M365 Provides

Effective email security is layered — each control addresses a specific attack vector that the others don't fully cover. Here's every layer Gradius deploys and manages as part of a complete email security program.

🔒
DMARC, DKIM & SPF — Stop Attackers Sending Email as Your Domain
DMARC (Domain-based Message Authentication, Reporting, and Conformance), combined with DKIM and SPF, forms the authentication layer that prevents attackers from sending emails that appear to come from your domain. Without DMARC enforced in reject or quarantine policy, anyone can send an email that says it's from yourcompany.com — to your clients, your employees, or your vendors. BEC attacks, vendor impersonation, and client fraud all rely on this gap. DMARC closes it. Gradius configures SPF records to define authorized sending sources, DKIM to sign outbound mail cryptographically, and DMARC to enforce what happens to mail that fails — published at reject or quarantine, not just monitor, which is where most partial implementations stall.
📧
Advanced Filtering Beyond Microsoft 365 — What EOP Misses
Microsoft 365's Exchange Online Protection (EOP) catches known malware, obvious spam, and threats in Microsoft's threat intelligence database. What it doesn't catch: novel phishing campaigns that haven't been catalogued yet, zero-day malicious URLs that were clean when scanned but weaponized after delivery, and sophisticated social engineering emails that don't contain malware at all. Advanced email filtering solutions — Mimecast, Proofpoint, and Graphus among them — use AI-based behavioral analysis, relationship intelligence, and independent threat intelligence feeds that operate independently of Microsoft's database. Gradius deploys and manages these solutions as a second filtering layer on top of M365, catching the threats that get through EOP.
🎭
BEC & Impersonation Detection — When the Email Looks Legitimate
Business email compromise doesn't carry malware — it carries a convincing request. A request to wire funds from someone who appears to be the CEO. An invoice from a vendor whose email address is one character off from the real one. A message from "ac********@*****ny.com" that routes to an attacker's account. Standard email filters don't catch these because there's nothing technically malicious about the email — the threat is in the social engineering. Impersonation detection uses relationship analysis (has this sender emailed your domain before?), domain similarity detection (flags lookalike domains), and display name spoofing detection to catch BEC attempts that pass every technical filter. Gradius configures and tunes these detections for your specific organization's communication patterns.
🔍
Anti-Phishing with Link & Attachment Sandboxing
Phishing emails deliver their payload in two ways: through malicious links that direct employees to credential-harvesting pages or drive-by download sites, and through malicious attachments that execute malware when opened. Time-of-click URL rewriting follows links at the moment an employee clicks them — not just at the moment of delivery — catching URLs that were clean when the email arrived but weaponized afterward. Attachment sandboxing detonates attachments in an isolated environment before they reach the recipient, catching malicious macros, PDFs with embedded scripts, and executable payloads that would execute on the employee's device. Gradius deploys and manages both controls as part of the email security program.
🔐
Email Encryption — Protect Sensitive Communications in Transit
Sensitive business communications — contracts, financial information, personal data, medical records, legal correspondence — transmitted via standard email travel unencrypted across the internet. Email encryption ensures that sensitive messages can only be read by the intended recipient, protecting against interception, satisfying HIPAA requirements for electronic PHI transmission, and meeting contractual obligations around sensitive data handling. Gradius configures policy-based email encryption that triggers automatically on sensitive content — so employees don't have to remember to encrypt manually and sensitive information doesn't travel unprotected because someone forgot a step.
📁
Email Archiving & Retention — Compliance & Legal Hold
SEC and FINRA require registered entities to retain business-related electronic communications for specified periods. HIPAA requires retention of communications containing PHI. Legal holds in litigation require preservation of email records. HR and employment law compliance requires documented communication records. Email archiving captures, indexes, and retains email in a tamper-evident repository that satisfies regulatory retention requirements and legal discovery obligations. Gradius configures email archiving as part of the email security program for organizations with retention obligations — financial services, healthcare, legal, and any business facing potential litigation — ensuring records are preserved correctly and retrievable when required.

Is Your Domain Protected by DMARC? Would Your Employees
Recognize a BEC Email From Your CEO?

Most organizations answer no to both — and most attackers know it. Book a free email security assessment and find out whether your DMARC is enforced (or just monitoring), what your advanced filtering catches versus what gets through, and whether your domain can be spoofed to send fraudulent emails to your clients right now.

Why NJ, NY & CT Businesses Choose Gradius for Email Security

Deployed Right. Tuned to Your Organization.
Managed Continuously — Not Set and Forgotten.

Email security tools are only as effective as their configuration and ongoing management. DMARC set to "monitor" doesn't stop spoofing. Advanced filtering with default tuning generates false positives that train employees to click "release from quarantine" on everything. BEC detection that isn't tuned to your organization's communication patterns misses the impersonation attacks specific to your firm. Gradius deploys, configures, tunes, and manages email security as a continuously maintained program — not a product installation that runs on defaults.

🔒
DMARC Implementation That Actually Enforces — Not Just Monitors
DMARC has three policy settings: none (monitor only — no action taken on failing mail), quarantine (failing mail goes to spam), and reject (failing mail is blocked entirely). The only setting that prevents domain spoofing is reject or quarantine. Most organizations that "have DMARC" are set to none — which means their domain can still be spoofed to send fraudulent emails to clients and employees. Gradius implements DMARC at the policy level that protects your domain, works through the SPF and DKIM alignment issues that cause legitimate mail to fail authentication, and gets to reject or quarantine without breaking email delivery.
🎭
BEC & Impersonation Detection Tuned to Your Business
Off-the-shelf BEC detection generates alerts based on generic impersonation patterns. Effective BEC detection knows your organization — which executives typically send wire instructions (and whether they ever do by email), which vendors regularly invoice by email, which clients communicate regularly. Gradius configures impersonation detection with your organizational context: protected sender lists, lookalike domain detection for your specific vendor relationships, and display name spoofing rules tuned to your executive team. The result is BEC detection that catches the specific attacks targeting your organization, not generic patterns that miss the personalized attacks.
📊
Email Threat Intelligence & Continuous Tuning
Email threats evolve. Phishing campaigns adapt to evade new filtering rules. BEC actors change tactics when detection rates rise. A static email security configuration becomes less effective over time as attackers learn what it catches and what it doesn't. Gradius monitors email security performance — review of quarantine queues, false positive rates, threat intelligence feeds, and emerging attack patterns — and adjusts configuration as the threat landscape shifts. This is the continuous management layer that distinguishes a managed email security program from a product that was deployed once and left on defaults.
📍
Integrated with the Full Security Program — Email + EDR + SOC
Email security is most effective as part of an integrated security program. When a phishing email gets through email filtering and an employee clicks, EDR on the endpoint is the next line of defense. When an employee reports a suspicious email, the report connects to email security analysis. When a BEC attempt is identified, the SOC can trace indicators of compromise across the environment. Gradius integrates email security with the full managed security program — so email, endpoint, and SOC work together rather than operating as disconnected tools.

FAQ

Common Questions About
Email Security Services

A complete email security program from Gradius includes: DMARC/DKIM/SPF configuration implemented at reject or quarantine policy (not monitor-only); advanced email filtering layer beyond Microsoft 365 EOP using Mimecast, Proofpoint, or Graphus with AI-based threat analysis and independent threat intelligence; BEC and impersonation detection tuned to your organization's specific executive team and vendor relationships; time-of-click URL rewriting and link sandboxing; attachment sandboxing; policy-based email encryption for sensitive communications; and email archiving for organizations with retention compliance requirements (SEC/FINRA, HIPAA, legal). All deployed, configured for your organization, and continuously managed.
Microsoft 365's Exchange Online Protection (EOP) provides a meaningful baseline — it catches known malware, spam, and threats in Microsoft's threat intelligence database. What it doesn't provide: independent AI-based behavioral analysis that catches novel threats not in Microsoft's database; relationship intelligence that flags emails from senders your organization has never communicated with; DMARC enforcement (M365 doesn't configure DMARC for your domain — that's your DNS responsibility); and BEC detection that understands your specific organizational structure and communication patterns. Advanced email security solutions used by Gradius have measurably different catch rates for sophisticated phishing and BEC compared to EOP alone. The specific gap depends on the sophistication of the attacks targeting your industry — financial services, real estate, and professional services firms face more targeted BEC than industries that see primarily commodity phishing.
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is the authentication protocol that prevents attackers from sending emails that appear to come from your domain. Without DMARC at a reject or quarantine policy, an attacker can send an email that says it's from yourcompany.com to your clients — requesting a wire transfer, updating payment instructions, or asking for sensitive information — and there's no technical barrier preventing that email from being delivered. This is the foundation of many BEC attacks: the spoofed email looks exactly like it came from the legitimate sender because it's using the legitimate domain name. DMARC at reject means those emails are blocked before they reach the recipient. For businesses in real estate, legal, financial services, or any field where clients trust emails from your domain with financial or sensitive decisions, DMARC at reject is not optional — it's the baseline that prevents your domain from being weaponized against your clients.
Gradius deploys and manages Mimecast, Proofpoint Essentials, and Graphus as primary advanced email security solutions, alongside other solutions appropriate to specific organizational environments. The selection depends on the organization's size, Microsoft 365 configuration, industry compliance requirements, and specific threat profile. Gradius is the management layer — we configure, tune, and continuously manage whichever solution is deployed for your organization, rather than prescribing one tool for every client regardless of fit. For organizations with existing email security solutions that aren't performing well, we also conduct email security assessments to identify why and what configuration changes or platform changes would improve outcomes.
DMARC/DKIM/SPF configuration is typically completed within one to two weeks — the DNS changes are straightforward once SPF and DKIM alignment is confirmed and the DMARC policy is set correctly. Advanced email filtering deployment (Mimecast, Proofpoint, or Graphus) typically requires one to two weeks for DNS routing changes, configuration, and initial tuning. BEC detection tuning requires two to four weeks of communication pattern analysis to configure organizational-specific rules accurately. Policy-based email encryption and archiving are typically deployed within one to two weeks. A complete email security program is operational within 30 days for most organizations, with BEC detection improving in accuracy over the first 60 days as tuning refines to organizational communication patterns.
No long-term lock-ins. We offer month-to-month and annual agreements. Email security is most effective as a continuously managed program — the threat landscape shifts, attack patterns evolve, and static configurations become less effective over time. Organizations stay with Gradius email security because phishing volumes decrease measurably, DMARC reports show the domain is protected, BEC detection catches impersonation attempts specific to their business, and email archiving satisfies compliance requirements without additional effort. We earn the renewal through performance.
