With the majority of cyber attacks infiltrating businesses through phishing emails, your mail systems need the advanced filtering and security services INSC provides — going far beyond what Microsoft 365’s default spam filter can catch. Advanced filtering, phishing protection, time-of-click URL scanning, and email encryption, deployed and managed by INSC.
Built-in email security simply doesn’t cut it anymore. Microsoft 365’s default filtering catches obvious spam — but sophisticated phishing campaigns, business email compromise, and malware-laden attachments get through every day. INSC’s Email Security Suite adds a dedicated advanced security layer that analyses every inbound and outbound message across multiple threat vectors simultaneously.
Where basic spam casts a wide net, spear phishing is extremely targeted — well-researched, focused on a specific individual, and sophisticated enough to fool even careful employees. Business email compromise attacks impersonate executives or trusted vendors to authorise wire transfers or data disclosures. INSC’s Email Security Suite identifies both, using sender analysis and display-name spoofing detection that Microsoft’s built-in tools regularly miss.
Attackers know that email security gateways scan links when email is delivered — so they use delayed-redirect techniques where the link is clean at delivery and turns malicious hours later, after filtering has already passed it. INSC’s time-of-click URL scanning re-evaluates every link at the exact moment a user clicks it — not when the email arrived.
When you use INSC’s email encryption services, your email communications will be unreadable to unauthorised users when sent over the internet. Your messages will be protected against interception or malicious attacks — and you can secure sensitive emails with passwords given only to trusted recipients, meeting the confidentiality requirements of HIPAA, legal privilege, and financial data regulations.
INSC's Email Security Suite deploys as a gateway layer on top of your Microsoft 365 or hosted email environment — enhancing protection without replacing your email platform.
INSC configures the email security gateway — routing inbound and outbound mail through the filtering platform without changing your users' experience.
Filtering policies configured for your environment — quarantine thresholds, encryption triggers, trusted sender lists, and executive protection rules established.
Every inbound and outbound message filtered in real time — spam blocked, phishing quarantined, URLs re-checked at click, attachments sandboxed.
INSC reviews quarantine reports, monitors for new attack patterns, and tunes policies over time — email security that improves as threats evolve.
That means every business. Email is how attackers reach your people — and how sensitive information leaves your organisation. Advanced email security is not optional.
BEC attacks targeting wire transfers and account changes are most commonly directed at financial services firms — advanced filtering is essential.
Privileged communications, wire transfer authorisations, and client confidentiality all depend on email security that actually stops sophisticated attacks.
Valuable IP and regulatory submissions communicated via email require both inbound phishing protection and outbound encryption.
HIPAA requires email encryption for PHI — INSC's policy-based encryption ensures compliance without requiring users to manually encrypt every message.
Email security controls are among the most commonly required by cyber insurers. INSC documents and evidences deployment for your policy application.
Accounting and consulting firms targeted for client data and financial information — spear phishing protection specifically designed for these attacks.
Default spam filtering is not enough to stop today's sophisticated phishing attacks. Block hackers before they even get to your company with INSC's advanced email security. Start with a free consultation.
