Block phishing, BEC, spoofing and malware-laced attachments before they reach inboxes. We deploy Microsoft Defender for Office 365, Google Workspace security, Proofpoint or Mimecast with SPF/DKIM/DMARC enforcement and user training.
Email Security covers the controls that stop malicious email from reaching users and protect outgoing email from being spoofed. The stack includes secure email gateways for inbound filtering (phishing, BEC, malware), authentication standards (SPF, DKIM, DMARC) to stop outbound spoofing, URL sandboxing, attachment detonation, and end-user awareness training.
Codesecure delivers email security as a managed solution covering platform deployment for Microsoft Defender for O365, Google Workspace, Proofpoint or Mimecast, full SPF / DKIM / DMARC rollout to enforcement, phishing simulation campaigns, and ongoing tuning. Named engineers handle DNS work, policy authoring and incident response when phishing waves hit.
Email is still the number one initial-access vector. The Verizon DBIR consistently ranks phishing and email-based social engineering as the top breach pattern. BEC (business email compromise) and invoice fraud cost Indian businesses hundreds of crores annually and target finance, HR and procurement teams specifically.
Email security is also compliance-relevant. RBI Cyber Security Framework expects DMARC enforcement for regulated entities. ISO 27001 Annex A.8.20-A.8.23 covers communications security. Indian fintech and banking partners increasingly require DMARC at p=reject before they will onboard new vendors. The ecosystem is moving from optional to mandatory.
Codesecure's managed email security solution covers the full inbound and outbound stack:
45-minute call with our email security lead. Bring your domain inventory and current gateway, leave with a phased deployment and DMARC roadmap. Instant response, no delay.
Book Free Strategy CallEvery Email Security engagement follows a 5-phase methodology from discovery through continuous operations:
Free 30-minute scoping call, NDA, domain and sender inventory, current gateway review, compliance obligations.
Platform selection, current SPF/DKIM/DMARC audit, sender legitimacy mapping, policy design.
Gateway provisioning, MX cutover, SPF/DKIM publishing, DMARC at p=none for telemetry.
Sender legitimacy validation, DMARC progression to p=quarantine then p=reject, policy tuning.
Ongoing incident response, monthly DMARC reports, quarterly phishing simulations, posture reviews.
Every Email Security engagement ships with the same operational handoff:
Most email security deployments reach enforcement within 1-2 weeks based on domain complexity. Instant response, no delay, we start architecture review same day or next business day after scoping.
Scoping, DNS audit, gateway provisioning, MX cutover, SPF/DKIM published, DMARC p=none.
Policy tuning, sender validation, DMARC progressed to p=quarantine, false-positive review.
Quarterly phishing simulations, DMARC progression to p=reject, monthly reports.
// Platforms & Tools We Support
30-minute call with our email security lead. Discuss your DMARC posture, BEC risk and gateway strategy with no sales pressure.
Schedule Free CallDepends on your mail platform. Microsoft Defender for Office 365 is the default for M365 tenants and integrates cleanly with Purview, Sentinel and Entra. Google Workspace native security covers most needs for Gmail-based orgs. Proofpoint and Mimecast lead the enterprise gateway market for advanced threat protection and large deployments. Sophos is cost-effective for SMBs. We help you pick based on platform, threat profile and budget.
DMARC tells receiving mail servers what to do with email that fails SPF or DKIM authentication, ranging from "none" (just report) to "quarantine" or "reject". Without DMARC at p=reject, attackers can spoof your domain to phish your customers, partners and employees. RBI now expects DMARC for regulated entities, and Indian banking / fintech partners increasingly require it for vendor onboarding.
Phased approach. We start at p=none for 30-60 days to collect telemetry on every system sending mail "as" your domain (including third-party SaaS like Mailchimp, ZohoCRM, HR platforms). After authenticating every legitimate sender via SPF and DKIM, we progress to p=quarantine, monitor for fallout, then move to p=reject. Most deployments reach p=reject in 60-90 days without breaking business mail flow.
Instant response, no delay. We respond within an hour during business hours, send fixed-scope proposal in 24-48 hours under NDA, and start architecture review same day or next business day after sign-off.
Yes. Quarterly phishing simulation campaigns using KnowBe4, Microsoft Attack Simulator or Proofpoint Security Awareness. Failed clickers get targeted bite-sized training automatically. We report click-rate trends to leadership and tune the program over time.
Standard scope. Anti-impersonation policies cover display-name spoofing, lookalike-domain detection, executive-mailbox protection, and out-of-band verification prompts on financial requests. We tune these specifically for finance, HR and procurement roles since those are the BEC targets.
Yes. Email security directly supports ISO 27001 Annex A.8.20-A.8.23 (network and communications security), SOC 2 CC6 (logical access), and RBI Cyber Security Framework email protection requirements. We produce audit-ready evidence including DMARC reports, gateway policy catalogue, phishing simulation records and incident logs.
