Security Implementation & Integration

EMAIL SECURITY

Stop phishing, BEC, and malicious attachments before the inbox. Faltrox deploys and tunes Trellix, Microsoft Defender for Office 365, Cisco, and SonicWall email security, and enforces SPF, DKIM, and DMARC so your domain cannot be spoofed.

Overview

Close the Front Door

Over 90% of intrusions still start with an email. We deploy and tune email security from Trellix, Microsoft Defender for Office 365, Cisco, and SonicWall so phishing, BEC, and malicious attachments are stopped before a user ever sees them.

Default tenant settings miss the attacks that matter: lookalike-domain BEC, credential-harvesting links that go live after delivery, and invoice fraud aimed at your finance team. We layer advanced threat protection, URL rewriting, sandboxing, and impersonation controls on top of a correctly configured mail flow.

We also fix the foundation most organisations skip: SPF, DKIM, and DMARC at enforcement, so your own domain can't be spoofed against your customers and partners.

Landscape

Protection Layers

Defence in depth from the DNS record to the inbox.

Domain Authentication

SPF, DKIM, and DMARC moved to p=reject with monitoring, so nobody can send as you.

Advanced Threat Protection

Sandboxing, safe attachments, and behavioural analysis for zero-day payloads.

URL Protection

Time-of-click rewriting and detonation for links weaponised after delivery.

Impersonation & BEC Defence

Executive, vendor, and domain-lookalike detection with finance-workflow safeguards.

Outbound DLP & Encryption

Policy-based encryption and data-loss controls on mail leaving the organisation.

Awareness & Response

Phishing simulation, one-click reporting, and automated purge of delivered threats.

Process

Deployment Method

Harden the foundation, then layer protection, then measure.

01
BASELINE
Audit current mail flow, tenant settings, authentication records, and recent phishing incidents.
02
AUTHENTICATE
Fix SPF and DKIM for every legitimate sender, then ramp DMARC from monitor to reject.
03
DEPLOY
Configure ATP, URL, and impersonation policies with staged rollout by user group.
04
TUNE
Review quarantine and false positives weekly; whitelist narrowly and document.
05
TRAIN
Run phishing simulations and roll out the report-phish button with a feedback loop.
06
OPERATE
Managed monitoring, threat purges, and monthly reporting on blocked attacks and user resilience.

Scope

Threats We Stop

The attacks that actually reach inboxes in 2026.

01critical

Business Email Compromise

CEO fraud, vendor invoice redirection, and payroll diversion targeting finance and HR.

02critical

Credential Phishing

M365 and SSO login lures, including MFA-bypass adversary-in-the-middle kits.

03high

Malicious Attachments

Macro documents, ISO/LNK droppers, and HTML smuggling carrying ransomware loaders.

04high

Domain Spoofing

Attackers sending as your brand to customers, partners, and your own staff.

Outcomes

Key benefits

Fewer phish delivered, fewer clicks, faster clean-up.

Measurable Phish Reduction

Layered controls plus DMARC enforcement typically cut delivered phishing by an order of magnitude within the first quarter, with monthly reporting to prove it.

Multi-Platform Expertise

Trellix, Microsoft Defender for Office 365, Cisco Secure Email, and SonicWall certified.

BEC-Specific Controls

Impersonation and payment-workflow safeguards, not just spam filtering.

Brand Protection

DMARC at reject stops your domain being used against your customers.

Compliance Evidence

Encryption and DLP records for DPDP, GDPR, and PCI DSS.

Automated Clean-Up

Delivered threats purged from every mailbox in minutes, not days.

FAQ

Common questions

01Which email security platforms do you deploy?

Trellix Email Security, Microsoft Defender for Office 365, Cisco Secure Email, and SonicWall Email Security. We work with your mail platform, whether Microsoft 365, Google Workspace, or on-premises Exchange.

02We already have Microsoft 365. Isn't email security built in?

The defaults are a baseline, not a configuration. Most tenants we assess have ATP policies partially applied, DMARC unenforced, and impersonation protection off. We tune what you own and add a layer only where it's needed.

03Why does DMARC matter?

Without DMARC at enforcement, anyone can send email that appears to come from your domain. Getting to p=reject stops brand spoofing against your customers and is increasingly required by major mail providers and cyber-insurance questionnaires.

04How do you handle BEC that has no malicious link or attachment?

Impersonation controls analyse sender identity, display-name lookalikes, domain similarity, and message intent, and we recommend process safeguards such as out-of-band verification for payment changes.

05Do you include user training?

Yes. Phishing simulation and a one-click report button are part of the rollout, with results feeding both user coaching and detection tuning.

06Can you operate it for us?

We offer managed email security operation including quarantine review, threat purges, DMARC monitoring, and monthly reporting, or we hand over a tuned configuration and runbooks.
