Gaps live in configuration
Many failures are configuration and coverage gaps mistaken for a missing product. Licenses without tuning leave the same risk on the table.
Email security that stops threats before they become incidents.
Arrow delivers layered messaging security with ongoing tuning and response, for the channel attackers still use first.
Managed long after install.
-
We layer defenses across every inbound and outbound message.
-
We continuously tune protection as new threats emerge.
-
Email is still attackers’ first move, so we run it as an operated control.
Why isn’t an email filter enough?
Because business email compromise often moves money without malware. Compromised mailboxes create rules, forwarding, and silent collection, and impersonation or delegation abuse looks like normal collaboration until the damage is done.
Beyond the phishing link
We watch for account takeover patterns, malicious mailbox rules, and unauthorized delegation, along with bad URLs.
A filter without response is a hope
Detection has to reach operators who can investigate and contain.
Operated controls on the first channel attackers use.
Layered filtering matters. So do mailbox-compromise detection, triage that respects your people, and a response path that doesn’t bounce between vendors.
What Arrow delivers
What does operated messaging security include?
Layered inbound filtering and outbound control for mail and collaboration, plus detection of the mailbox compromise a filter doesn’t catch. Investigation and containment run with operators who know your tenant.
- Inbound filtering, outbound control
- Mailbox-compromise detection
- Operators who know the tenant
Tied to identity
Why does mailbox takeover belong with identity?
Because messaging compromise often is identity compromise. Messaging Security stays on the same floor as Identity Security and Endpoint Security, so an email incident moves to containment without a handoff between vendors.
- Same floor as identity
- Endpoint follow-through
- No handoff between vendors
Why Arrow
Why treat email as an operated control?
Because many “tool gaps” are configuration gaps. Arrow tunes policy against your threat profile on a named team, so false positives and missed threats are handled as routine operations work.
- Ongoing tuning after go-live
- Configuration as security
- A named team owns the policy
What BEC looks like
past the link.
The patterns a filter misses.
Business email compromise and mailbox abuse often look like normal collaboration. These are the patterns the program watches for.
1 / 4
Assess, harden, monitor, contain, then feed it back.
Configuration and coverage come first, because that’s where many messaging programs fail.
Assess
We assess current mail protection, starting with configuration and coverage gaps.
Harden configuration
Policies are tuned to how the tenant actually works, closing the gaps that make good tools fail.
Monitor
We watch for BEC and phishing patterns, including mailbox rules and delegation.
Investigate and contain
Operators who know the tenant investigate and contain, so an email incident ends in containment and hardening.
Feed lessons back
Lessons improve your identity and Endpoint Security programs, aligned with Managed Microsoft 365 and Managed Microsoft Security when those are in scope.
Identity Security
Access policy that follows the user, watched by the same floor.
Endpoint Security
Operated policy and response on every device that touches the estate.
Threat Management
Detection and response from the same operators, every time.
Network Security
Hardened firewalls and segmentation across the fabric you run.
Managed Microsoft Security
Operated Microsoft security controls alongside messaging, identity, and endpoint when the Microsoft stack is in scope.
FAQs
Is messaging security only email filtering?
It covers inbound filtering and outbound control for mail and collaboration, with tuning after go-live. The program is operated posture that keeps adjusting.
Why do messaging programs fail if a tool is already licensed?
Failures are often configuration and coverage gaps. Licenses without operators and without tuning against your threat profile leave the same risk on the table.
Who tunes messaging policy?
Arrow, against your threat profile, on a named team, so false positives and missed threats are treated as routine operations work.
How does a messaging incident move to the endpoint team?
Messaging, identity, and endpoint sit on the same architecture, so response is not a handoff between vendors. One accountable floor when Arrow runs the related controls.
Does this replace our collaboration platform?
No. The work protects mail and collaboration paths you already use. Platform replacement is out of scope unless the tool itself cannot support the required controls.
