Your Email Is The #1 Target. Here's How We Defend It.

Email isn't just where work happens — it's where attackers go first. ECSG layers six independent defenses across your mailbox, endpoints, and network perimeter, so one bad click is never enough to breach your business.

The Risk

Email Is Where Cybercrime Actually Happens.

Ransomware, credential theft, and wire fraud almost always start the same way — with a single email that looks like it belongs in your inbox.

Layer 01 · Foundation

Outlook & Native Email Authentication

Before any advanced tool gets involved, we make sure the basics are configured correctly — because most email spoofing succeeds when these are missing, weak, or misconfigured.

Outlook
Outlook

The inbox itself — the front door attackers target most.

MX
MX Records

Direct where your mail is delivered — the entry point we lock down first.

SPF
SPF

Declares exactly which servers are allowed to send email for your domain.

DKIM
DKIM

Digitally signs outgoing mail so recipients can verify it wasn't altered.

DMARC
DMARC

Tells receiving servers what to do with mail that fails SPF/DKIM — and reports back to us.

AD
Autodiscover

Automatically and securely configures Outlook with the correct server settings.

Layer 02 · Advanced Email Security

Proofpoint: The Advanced Layer Native Security Can't Match

SPF, DKIM, and DMARC stop obvious spoofing — but they don't stop a convincing, targeted attack from a lookalike domain. That's where Proofpoint takes over.

Targeted Attack Protection

Detects and blocks spear-phishing and impersonation attacks built specifically to fool your employees — not just generic spam.

URL Rewriting & Sandboxing

Every link is rewritten and checked in real time at the moment it's clicked, not just when it was delivered.

BEC & Impersonation Defense

Flags emails that mimic your executives or vendors before a wire transfer or credential request ever reaches an inbox.

Attachment Analysis

Malicious attachments are detonated and analyzed in an isolated environment before they ever reach a user.

Global Threat Intelligence

Backed by threat data from billions of messages processed daily across Proofpoint's global customer base.

Email Continuity

If a threat is caught, delivery is stopped — without disrupting the legitimate email your team relies on.

Layer 03 · Endpoint Detection & Response

SentinelOne: The Hidden Gem of Our Stack

Even if a threat gets past email, it still has to survive the endpoint. Most people have never heard of SentinelOne — and that's exactly why it's so effective.

AI-Driven Detection

An autonomous AI agent runs directly on every endpoint, spotting malicious behavior in real time — with or without an internet connection.

One-Click Rollback

If ransomware slips through, SentinelOne can roll a device back to its pre-attack state in seconds — no full reimage required.

Autonomous Response

Threats are isolated and neutralized automatically, without waiting on a human analyst to act first.

Behavioral Analysis

Detects fileless malware and zero-day attacks by watching what a process does, not just matching known signatures.

Full Attack Storyline

Every incident is reconstructed into a visual timeline, so we know exactly how an attack started and what it touched.

Cross-Platform Coverage

The same protection extends across Windows, macOS, and Linux devices in your environment.

Layer 04 · DNS & Browser Security

DefensX: DNS Filtering & Credential Protection

Most attacks that survive email still need your browser to finish the job — a malicious link, a fake login page, a drive-by download. DefensX shuts that path down at the browser and DNS layer.

DefensX
DefensX layered security tiers

Layered protection tiers — DefensX scales from core DNS filtering up to full browser isolation and Zero Trust access, so protection grows with your risk profile.

DefensX policy-aligned browser protection

Policy-aligned browser protection — content and file filtering, plus session and credential guarding, applied automatically per user and group policy.

DefensX human risk management dashboard

Human risk dashboard — real-time, automated visibility into risky behavior and vulnerabilities across your organization.

Security Groups

Policies are applied by group — department, role, or risk level — instead of configuring every user one by one.

Custom URL Groups

We build allow/block lists specific to your business — vendors, tools, and sites your team actually needs.

Filtering Categories

Malicious domains, phishing infrastructure, adult content, gambling, and dozens of other risk categories, filtered by policy.

Credential Protection

Detects when a corporate password is typed into a non-corporate site — stopping credential reuse and phishing pages in the moment.

Remote Browser Isolation

Risky or unknown sites are rendered in an isolated cloud container — nothing malicious ever touches the actual device.

Zero Trust Access

Secure access to internal apps without a legacy VPN — extending protection to remote and hybrid teams.

Layer 05 · Network Perimeter

Firewall & Security Package: Guarding the Perimeter

Everything above this point protects a mailbox, a browser, or a device. The firewall protects the network itself — the boundary between your business and the open internet. It sits here deliberately: after the user-facing layers, because it isn't guarding a person's inbox or browser — it's guarding every device, server, printer, and camera on the network at once, including the ones that can't run an agent.

The Security Package, Licensed On Every Firewall
Gateway Anti-Virus

Scans traffic at the gateway and blocks known malware, worms, and Trojans before they ever reach a device on the network.

Anti-Spyware

Blocks the installation of spyware at the network level and disrupts covert communications from spyware already present.

Intrusion Prevention

Deep packet inspection scans every connection in real time for exploits, buffer overflows, and known attack signatures — and blocks them automatically.

Application Control

Granular policies decide which applications are allowed to run on the network at all, and how much bandwidth they're permitted to use.

Application Visualization

Real-time, real-world visibility into exactly which applications are running across the network — not just what's technically allowed.

Content Filtering — Premium Edition

Category-based web filtering enforced network-wide, blocking malicious, inappropriate, and non-business categories of sites for every device behind the firewall.

  • VPN & Secure Remote AccessEncrypted tunnels let remote and hybrid employees reach internal resources without exposing the network directly to the internet.
  • Network SegmentationServers, workstations, guest Wi-Fi, and IoT devices are isolated from each other, so a breach in one zone can't spread to the rest.
  • Outbound Threat ControlJust as important as blocking attacks coming in: stopping an already-compromised device from calling out to attacker infrastructure.
  • Full Visibility, Zero Blind SpotsDevices that can't run a security agent — printers, cameras, smart thermostats — are still covered, because protection lives at the network level.

Where This Connects

Every event the firewall sees — blocked connections, intrusion attempts, outbound anomalies — is streamed as a continuous log feed into RocketCyber / Kaseya MDR. The firewall doesn't just defend the perimeter on its own; it becomes another set of eyes for the SOC below, correlated in real time against what's happening on your endpoints and in Microsoft 365.

🌐 Configured, licensed, and maintained remotely — no site visit needed
Layer 06 · Managed Detection & Response

RocketCyber (Kaseya MDR): Our Fortress

Every layer above generates signals. This is where those signals meet a real Security Operations Center — human analysts watching, validating, and acting, 24 hours a day.

Kaseya MDR (formerly RocketCyber) dashboard

The MDR console — formerly RocketCyber, now Kaseya MDR: an alert-centric SOC view monitoring endpoints, Microsoft 365, and firewalls simultaneously.

Proactive threat hunting

Proactive threat hunting — analysts apply an extensive threat-indicator database to catch what automated tools alone would miss.

24/7 SOC Monitoring

Real security analysts — not just automation — review and validate every alert, every hour of every day.

AI-Enhanced Triage

AI correlation cuts through noise and false positives, so analysts spend their time on real threats, not alert fatigue.

Firewall Log Ingestion

RocketCyber / Kaseya MDR ingests the log feed directly from your firewall, correlating network-edge events with endpoint and email activity in one view.

Endpoint, M365 & Firewall

The three attack surfaces that matter most for an SMB, monitored together instead of in separate blind spots.

Ransomware Containment

Suspicious processes are killed and endpoints isolated automatically the moment ransomware behavior is detected.

Ready-to-Act Tickets

When something needs attention, ECSG gets a precise, actionable ticket — not just a raw alert to decipher.

400-Day Log Retention

Long-term visibility for investigations, audits, and compliance — well beyond what most tools retain.

Why This Is Our Fortress

Tools alone don't stop breaches — attention does. RocketCyber / Kaseya MDR is the layer where every signal from Outlook, Proofpoint, SentinelOne, DefensX, and your firewall converges into one place, watched by people whose only job is to catch what automation missed.
