Phishing still gets through. You know it does.
Your M365 spam filter catches obvious junk. The email impersonating your CFO, the invoice redirect from a spoofed supplier, the credential harvesting link on a legitimate-looking page. Those get through. Edge7 Networks layers dedicated email security on top of what you already have. Managed for you, without adding another console to your team's day.
Native filters handle spam. They were not built to stop targeted attacks.
Microsoft 365 includes Exchange Online Protection, and some licences include Defender for Office 365. These tools do a reasonable job of filtering bulk spam and blocking known malicious attachments. They were designed to handle volume threats at scale.
Targeted attacks work differently. A Business Email Compromise email contains no malware, no malicious link, and no attachment. It passes every rule check because the threat is in the words and the request, not the technical structure. An attacker impersonating your CFO at 4:45 on a Friday afternoon, asking finance to process an urgent transfer before the weekend, does not trigger a filter.
The question is not whether M365 has email security built in. It does. The question is whether what is built in is sufficient for the attacks that are actually targeting your organisation.
A finance team member receives an email from what appears to be the FD. The display name is correct. The message asks them to authorise a payment before end of day. The actual sending domain is a one-character variation of the real one. No attachment, no link, no malware. Nothing for a native filter to catch.
BEC bypasses native detection
Business Email Compromise attacks contain no malicious payload. Standard filters look for technical indicators. BEC attacks are socially engineered to look legitimate at every technical check.
Credential harvesting on trusted infrastructure
Phishing pages are increasingly hosted on legitimate cloud services, making URL reputation checks ineffective. By the time a URL is flagged, the credential has already been stolen.
Your domain can be spoofed
Without properly configured DMARC, DKIM, and SPF, attackers can send email that appears to come from your domain. Your customers and partners receive phishing emails that look like they are from you.
Users are the last line of defence, by default
Without regular, realistic phishing simulations and awareness training, your users are making judgements they are not equipped to make. One click is all it takes to give an attacker a foothold.
What you get when you add managed email security.
Targeted phishing intercepted before it reaches your inbox.
Dedicated email threat intelligence goes further than reputation-based filtering. Emails are assessed against threat patterns specific to your industry and organisation, not just against lists of known bad senders.
URLs are inspected at click time, not just at delivery. A link that appears clean when the email arrives can be checked again the moment a user clicks, catching fast-flux phishing pages that are stood up after the email clears initial scanning.
- Attachment sandboxing detonates suspicious files before delivery to the inbox
- Domain lookalike detection catches variants designed to appear legitimate at a glance
- Display name deception flagged when the visible name does not match the actual sending domain
BEC flagged before the request reaches anyone with authority to act.
Business Email Compromise works by appearing legitimate. The email has no attachment, no malicious link. It passes every technical check. Catching BEC requires a different approach: analysis of communication patterns, sender behaviour, and request context rather than content signatures.
When an email arrives appearing to be from your FD requesting an urgent payment, the platform assesses whether the communication pattern is consistent with how that sender normally communicates, whether the request type is unusual, and whether the sending infrastructure matches what would be expected.
- Lookalike domain detection flags one-character variations of trusted domains
- Impersonation detection applies to internal executive names and trusted external contacts
- Unusual request context flagged even when sender identity appears valid
Your domain stops being a tool for attackers.
Without DMARC configured and enforced, anyone can send an email that appears to come from your domain. Your customers, suppliers, and partners can receive phishing emails that pass every check on their end because the sending domain appears to be legitimately yours.
Edge7 Networks configures DMARC, DKIM, and SPF as part of the managed service, moving your domain from no policy or monitoring to full enforcement. Once in place, the configuration is monitored on an ongoing basis so that changes to your email infrastructure do not inadvertently open gaps.
- DMARC moved from none or monitor to reject or quarantine policy
- DKIM signing configured for all outbound mail streams
- SPF records maintained and monitored for drift as your infrastructure changes
Users become an active layer in your email defence.
Technical controls catch most threats. The ones that get through are specifically designed to bypass them. Your users are the final check. Equipping them to make better decisions under pressure, rather than relying on instinct, is the most effective way to reduce the risk of a successful attack.
Simulated phishing campaigns send realistic but safe phishing emails to your users. Those who engage receive immediate, in-context education rather than a retrospective discussion. Simulations are tailored to the attack patterns most relevant to your organisation and sector.
- Phishing simulations mimic real-world attack types including invoice fraud and credential harvesting
- Training modules delivered at the moment of failure, not in a quarterly reminder
- Monthly reporting tracks improvement and identifies users who need additional support
No additional console. No additional workload for your team.
Adding a new security tool to your environment only helps if someone is looking after it. A platform that is deployed and left to default settings provides a fraction of its potential value. Edge7 Networks manages the email security platform end to end: configuration, ongoing tuning, policy updates, and monitoring.
Your team does not need to log into another dashboard. Edge7 Networks provides a monthly summary covering what was blocked, what phishing simulations ran, how users responded, and what changed in the configuration. You stay informed without taking on the operational overhead.
- Platform configured for your environment from day one, not left on defaults
- Ongoing tuning as your organisation changes and new attack patterns emerge
- Monthly summary report with blocked volume, simulation results, and recommended actions
Layered on top of M365 and Google Workspace. Not a replacement.
Your users continue to send and receive email through the platform they already use. Advanced email security does not change that. It adds a layer of protection that inspects messages before they reach inboxes, without disrupting workflows or requiring any changes to how your team uses email.
Native email platform
Exchange Online Protection and Gmail spam filtering. Effective against bulk threats and known malicious content. Not designed for targeted attacks, BEC, or credential harvesting on legitimate infrastructure.
Advanced threat protection
Dedicated email security platform that adds phishing interception, BEC detection, click-time URL scanning, attachment sandboxing, DMARC enforcement, and impersonation analysis on top of your existing infrastructure.
Edge7 Networks managed service
Configuration, tuning, monitoring, and reporting handled by Edge7 Networks. Your team receives a monthly summary. No additional console, no additional workload.
Platform choice is driven by detection capability and your existing environment. Edge7 Networks supports both Microsoft 365 and Google Workspace. The advanced protection layer integrates directly with your existing email platform without requiring migration or changes to how your team sends and receives email.
Email security that works with the rest of your security programme.
Managed from day one
The platform is configured for your environment when it is deployed, not left on defaults and handed back. Edge7 Networks handles ongoing tuning, policy updates, and monitoring. You do not manage another tool. You receive a monthly summary of what was blocked, what changed, and what to know.
Integrated with your wider security
Email is one entry point. The same Edge7 Networks team managing your email security also manages SOC/SIEM monitoring, MDR response, and identity protection. When an email-borne threat triggers a wider investigation, the context is shared across your security programme rather than siloed in a separate platform.
Works alongside what you already have
No platform migration. No change to how your users send and receive email. The additional protection sits on top of Microsoft 365 or Google Workspace. Your users keep their existing email addresses, clients, and workflows. Zero disruption to day-to-day operations.
