SPF, DKIM, DMARC, anti-phishing training, and 24/7 monitoring — all managed by IT Center so your team stays protected and your inbox stays clean.
IT Center deploys a defense-in-depth approach to email — every message evaluated at multiple checkpoints before it ever reaches your inbox.
We audit your DNS records and implement all three email authentication standards — Sender Policy Framework, DomainKeys Identified Mail, and Domain-based Message Authentication — to eliminate domain spoofing and prevent impersonation attacks at the source.
We deploy enterprise-grade gateways — Microsoft Defender for Office 365, Proofpoint, or Mimecast — to scan every inbound message for malicious URLs, attachments, and lookalike domains. Threats are quarantined before users ever see them.
We run controlled, realistic phishing campaigns against your own employees — then use the results to drive targeted security awareness training. Employees who click get immediate coaching. Track improvement over time with detailed reporting dashboards.
Immutable, tamper-proof email archives retained for 7+ years satisfy HIPAA, SOC 2, and litigation hold requirements. Instantly retrieve any message via full-text search. Legal hold workflows freeze specific mailboxes for eDiscovery without disrupting daily operations.
Protect sensitive communications with Transport Layer Security (TLS), S/MIME certificate-based encryption, and Microsoft 365 Message Encryption for end-to-end protection. Ideal for sending PHI, financial data, legal documents, and confidential contracts without risk of interception.
Multi-layer AI-powered filtering catches spam, ransomware payloads, malicious macros, and zero-day attachments with industry-leading accuracy. Sandboxing detonates suspicious files in an isolated environment before delivery, eliminating risk without user intervention.
Email is the entry point for over 90% of cyberattacks against businesses. These are the threats your team faces every day.
Attackers impersonate executives, vendors, or partners and trick employees into wiring funds or sharing credentials. BEC is the costliest email crime category tracked by the FBI — and it requires zero malware to execute.
Attackers study your organization's email patterns, then craft convincing messages that appear to come from leadership. Urgent wire transfer requests, fake invoice approvals, and payroll redirect scams devastate businesses that lack email authentication controls.
Convincing login pages mimicking Microsoft 365, DocuSign, or your bank harvest usernames and passwords from unsuspecting employees. One compromised credential opens your entire network, email archive, and cloud storage to attackers.
"The average business email compromise incident costs $125,000 — far exceeding any email security investment. For most small businesses, a single successful BEC attack is company-ending."

IT Center is a Microsoft Cloud Solution Provider (CSP) partner. We deploy Microsoft 365 with Exchange Online as the email foundation, then layer Defender for Office 365, MXGuardDog filtering, encryption, archiving, and managed SMTP relay on top. The result: business email that auditors, attorneys, and cyber insurers all accept — without the cost or complexity of building it yourself.
Full Microsoft 365 deployment as a CSP partner: Exchange Online mailboxes, Teams, OneDrive, SharePoint, and Defender bundled at the right SKU for your business size and compliance posture.
Inbound mail flows through MXGuardDog spam/phishing filtering before hitting Microsoft Defender for Office 365 — two independent inspection layers catch what either alone would miss.
Authentication records configured, monitored, and tuned by us. We move you from p=none to p=quarantine to p=reject on a controlled timeline that protects deliverability.
For application-generated email (forms, alerts, billing, notifications), we set up authenticated SMTP relay through providers like SendGrid, Postmark, or Microsoft Direct Send — with deliverability monitoring and DMARC alignment baked in.
Auditors, cyber insurers, and enterprise customers expect Microsoft 365. Running it puts you on the same footing as the Fortune 500.
As your Microsoft CSP, we provision licenses, handle billing, and provide first-line support. One invoice for licenses, mailboxes, security, and managed services.
Email emergencies don’t wait for business hours. Our operations team is reachable around the clock for delivery issues, account compromise, or security alerts.
Moving from Google Workspace, GoDaddy, or self-hosted Exchange? We handle the full migration — email, contacts, calendar, public folders — with planned cutover and zero data loss.
Our no-cost email security assessment uncovers gaps attackers exploit before they can cause damage. Here's exactly what we review:
We check whether your Sender Policy Framework record exists, is correctly formatted, and doesn't contain the insecure ~all softfail mechanism that allows spoofed messages to pass.
We verify your DMARC record is published, set to enforce (p=reject or p=quarantine), and includes a reporting URI so you receive aggregate and forensic reports from receiving mail servers.
We confirm your DKIM signing keys are published in DNS, match your mail server configuration, and use a modern key length (2048-bit minimum) that resists brute-force attacks.
We audit your MX records to confirm mail is routing through your chosen gateway, not directly to an exposed mail server — a common misconfiguration that bypasses all filtering.
We evaluate your current spam/phishing gateway — whether that's Microsoft Defender, a third-party solution, or nothing at all — and assess its effectiveness against current threat vectors.
We determine whether your current email retention policies meet applicable regulatory requirements (HIPAA, SOC 2, FINRA, state-level mandates) and whether existing archives are tamper-proof and searchable.
We scan breach databases for employee email addresses and passwords that have already been compromised and are available for purchase on dark web marketplaces — often without the business's knowledge.
We assess your organization's current phishing awareness posture and can run an initial controlled simulation to establish a baseline click rate — the starting point for your employee training program.
Email threats are evolving daily. IT Center's free assessment delivers a prioritized remediation roadmap — at no cost and no commitment. Most audits are completed within 48 hours of your request.
