Business Email SecurityStop Phishing. Prevent Spoofing.
Catch CEO Fraud Before It Costs You.

Microsoft 365 includes baseline email security through Exchange Online Protection (EOP) — it filters known spam, blocks malware with known signatures, and catches phishing that's been catalogued in Microsoft's threat database. What it doesn't catch reliably: sophisticated phishing campaigns using novel techniques that aren't yet in Microsoft's database; business email compromise (BEC) attacks that use social engineering rather than technical malicious content; zero-day malicious links that appear clean at email delivery but activate later; and domain spoofing when DMARC isn't configured correctly. For most NJ, NY & CT businesses, Microsoft 365's default protection is a floor, not a ceiling. Gradius adds the advanced filtering, DMARC configuration, BEC detection, and account security that makes email genuinely protected rather than nominally secured.

Business email compromise is a cyberattack that uses impersonation rather than malware — the attacker impersonates a trusted person or organization to trick an employee into taking a financially damaging action: wiring money to a fraudulent account, paying a fake invoice, changing payment details for a real vendor, or revealing sensitive information. The FBI consistently ranks BEC as the highest-dollar cybercrime category — it generates more financial losses than ransomware, malware, and all other cybercrime types combined. BEC works because it exploits trust rather than technology. An employee who receives what appears to be an urgent wire transfer request from the CEO is more likely to act on it than to scrutinize the email address it came from. BEC detection addresses this by flagging emails that use executive names from unknown addresses, come from domains that look similar to known vendors but aren't quite right, or request actions that fall outside normal communication patterns.

A compromised business email account gives an attacker access to everything the account contains: all email history, calendar, contacts, and any files shared through Microsoft 365. Attackers who compromise business email typically don't immediately reveal themselves — they read email for days or weeks to understand communication patterns, ongoing transactions, and financial activity before using the account for fraud. During this time they may forward copies of incoming email to an external address, set up rules that hide their activity, and identify the specific transactions to target. By the time a business realizes the account was compromised, the attacker has already gathered significant intelligence. MFA prevents this by requiring a second factor beyond the password — so even if credentials are stolen, the attacker can't log in without the second factor the employee holds.

MFA can be enforced on all Microsoft 365 accounts within one to two days — it's a configuration change that takes effect immediately once enabled. DMARC, DKIM, and SPF configuration typically takes one to two weeks — DNS changes must propagate, and existing email systems need to be verified as legitimate senders before the policy is enforced to avoid blocking legitimate email. Advanced phishing filtering deployment (Mimecast, Proofpoint, or Graphus) typically takes one to two weeks for DNS routing, configuration, and initial tuning. BEC detection tuning — configuring the specific executive roster, vendor relationships, and communication patterns for your organization — is completed within two to four weeks and improves in accuracy over the first 30 to 60 days. Most organizations have comprehensive email security in place within 30 days of starting the program.

No long-term lock-ins. We offer month-to-month and annual agreements. Businesses stay with Gradius email security because phishing volumes drop measurably, DMARC reports show the domain is protected, BEC attempts specific to the business are being flagged, accounts are secured with MFA, and email archiving satisfies compliance requirements without additional effort. We earn the renewal every month through performance.

We serve 12+ industries in NJ, NY & CT including healthcare, legal, financial services, construction, manufacturing, real estate, insurance, architecture, professional services, restaurants, nonprofits, and general business — each with specialized compliance and operational expertise built in.
