Why Cybersecurity Can't Wait

Cyber attacks on SMBs have tripled in recent years. Most breaches are preventable with the right layers in place.

01

Phishing & Social Engineering

Attackers impersonate vendors, partners, and executives to steal credentials and trigger wire transfers.

02

Ransomware & Malware

Encrypted files, operational downtime, and ransom demands — often entering through email or unpatched endpoints.

03

Identity & Account Compromise

Stolen credentials used to access Microsoft 365, Azure, and internal systems — often going undetected for weeks.

Our 5-Layer Security Stack

Effective cybersecurity is never a single product — it's a coordinated set of layers. Each layer addresses a distinct attack surface and works in concert with the others.

Email Security
Microsoft Defender for M365 Proofpoint Essentials MX / SPF / DKIM / DMARC
The #1 attack vector. We harden your email perimeter with proper DNS authentication records (SPF, DKIM, DMARC) and advanced filtering to stop phishing, spoofing, malware, and BEC attacks before they reach your inbox.
Endpoint Protection
Windows Defender / MDE SentinelOne RocketCyber XDR
Every workstation, laptop, and server is a potential entry point. We deploy endpoint agents that detect malware, suspicious processes, and anomalous behavior in real time — with automated response capabilities.
SOC & XDR Monitoring
RocketCyber Managed SOC Microsoft Sentinel
24/7/365 threat detection, triage, and escalation by a dedicated security operations team. Security events across endpoints, cloud, and network are correlated using the MITRE ATT&CK framework.
DNS & Web Filtering
DefensX Microsoft Defender for DNS
Block malicious domains, command-and-control callbacks, botnet traffic, and access to harmful or non-compliant websites — before a connection is even established. DefensX adds browser-level zero-trust isolation.
Identity & MFA
Microsoft Entra ID Conditional Access MFA / SSPR
Identity is the new perimeter. We configure MFA, Conditional Access policies, and monitor all Microsoft 365 login events for suspicious activity, impossible travel, and compromised credential alerts.

MX, SPF, DKIM & DMARC — What They Are and Why They Matter

Email authentication is the foundation of any cybersecurity program. Without these four DNS records properly configured, your domain is wide open to spoofing and impersonation.

The 4 DNS Records That Protect Your Email

Most SMBs have an MX record pointing email to Microsoft 365 — but that's only one piece of the puzzle. ECSG audits and configures the full set of email authentication records to ensure your domain cannot be impersonated.

We also layer Proofpoint Essentials or Microsoft Defender for Office 365 on top of these records for advanced threat filtering, sandboxing of attachments, and URL rewriting.

MX Record SPF DKIM DMARC Anti-Spoofing Anti-BEC Attachment Sandboxing URL Rewriting
Email Authentication Records
MX Record
Routes inbound email to your mail server (e.g., Microsoft 365)
SPF
Lists authorized sending IPs — rejects unauthorized senders
DKIM
Adds a cryptographic signature — verifies message integrity
DMARC
Enforces SPF/DKIM policy — quarantine or reject failing mail

Every Device. Every User. Protected.

We deploy and manage endpoint protection across Windows, macOS, and mobile devices — choosing the right tool for each client's risk profile and budget.

Microsoft Built-In

Windows Defender / MDE

Microsoft Defender for Endpoint (MDE) is the built-in enterprise EDR included with Microsoft 365 Business Premium and higher. When properly configured and managed, it provides robust threat detection, attack surface reduction, and automated investigation.

  • Real-time malware detection and removal
  • Attack Surface Reduction (ASR) rules
  • Cloud-delivered protection via Microsoft cloud
  • Tamper protection and controlled folder access
  • Integrated with Microsoft Intune and Entra ID
Advanced EDR / AI-Powered

SentinelOne

For clients requiring the highest level of endpoint protection, SentinelOne delivers autonomous AI-powered threat detection and response. It acts in real time — no human needed to isolate and remediate a compromised device.

  • Behavioral AI — detects unknown threats (zero-day)
  • Automated rollback — undoes ransomware damage
  • Full EDR telemetry and forensic timeline
  • Works on Windows, macOS, Linux, and cloud workloads
  • Single console with multi-tenant management
Managed SOC + XDR for MSPs

RocketCyber

RocketCyber is ECSG's primary SOC platform — a cloud-based Managed Security Operations Center designed specifically for MSPs. It aggregates telemetry from endpoints, Microsoft 365, and network devices into a single correlation engine monitored 24/7.

  • 24/7/365 SOC team triage and escalation
  • MITRE ATT&CK Framework-based detections
  • Microsoft 365 and Entra ID security monitoring
  • Lightweight agent — no on-premise hardware
  • Alerts on log clearing, failed logins, suspicious tasks
Browser Isolation + DNS Filtering

DefensX

DefensX is a zero-trust browser and DNS security platform that blocks threats at the DNS level and isolates risky web sessions before malicious code can touch the endpoint. Ideal for remote workers and high-risk browsing environments.

  • DNS-layer threat blocking (pre-connection)
  • Remote browser isolation for high-risk sites
  • Web content filtering and policy enforcement
  • Protects unmanaged devices (BYOD)
  • No hardware — cloud-delivered, instant deployment

Microsoft Native vs. Extended Security Stack

Depending on your organization's risk tolerance, compliance requirements, and budget, ECSG can deploy a Microsoft-first security model or a best-in-class extended stack using third-party vendors.

Foundation Tier
Microsoft Native Stack
Excellent baseline coverage for most SMBs already using Microsoft 365 Business Premium. Managed and configured by ECSG.
  • Microsoft Defender for Endpoint (EDR)
  • Defender for Office 365 (email filtering)
  • Microsoft Entra ID + Conditional Access + MFA
  • Microsoft Intune (device management)
  • Microsoft Sentinel (SIEM / log correlation)
  • SPF / DKIM / DMARC configuration
  • Microsoft Secure Score management

Your Security is Our Responsibility

We don't just sell software — we deploy, configure, monitor, and continuously improve your security posture as part of a managed service engagement.

MSP-Grade Tools

We use enterprise security platforms built for MSPs — multi-tenant, cloud-managed, and purpose-built for the SMB market.

24/7 SOC Coverage

Threats don't keep business hours. Our SOC team monitors your environment around the clock and escalates real incidents — not false alarms.

True Multi-Layer Defense

No single product stops every attack. We engineer overlapping layers so that if one control fails, the next one catches the threat.

Compliance-Ready

Our security stack supports HIPAA, SOC 2, CMMC, and NIST frameworks — with documentation and reporting to back it up.

Security Onboarding in 5 Steps

We follow a structured approach to assess, design, and deploy your security stack — minimizing disruption and maximizing protection from day one.

01

Security Assessment

We audit your current environment, email records, endpoint posture, and identity configuration.

02

Risk Report

We identify gaps, vulnerabilities, and priority areas — presented in a clear report with recommended actions.

03

Stack Design

We select the right combination of tools for your size, risk profile, and compliance requirements.

04

Deployment

We deploy agents, configure DNS records, enable MFA policies, and activate SOC monitoring — fast and with minimal disruption.

05

Ongoing Management

Continuous monitoring, monthly reporting, policy tuning, and annual security reviews — security is never a one-time project.
