Barracuda
Most of what is sent to you is not worth receiving. Some of it is designed to cost you money.
Barracuda filters the flood before it reaches anyone, blocking spam and malware at volume while watching for the smaller number of messages built to impersonate, defraud, or take over an account. It also backs up what Microsoft 365 does not, which surprises most businesses when they first go looking for it.
Volume is the nuisance. Targeting is the expensive part
Spam wastes time. A single well-researched impersonation costs real money, and the two require completely different defenses. Filtering at volume does not catch a message written specifically for one finance manager, and neither does a tool that only inspects attachments.
The flood that never stops
Unfiltered, the majority of inbound mail is unwanted. Beyond the wasted attention, every extra message is another chance for someone to click the wrong one on a bad day.
Fraud that names your people
Impersonation attacks reference real colleagues, real invoices, and real projects. They contain no malware at all, which is exactly why traditional scanning lets them through.
Data walking out quietly
Sensitive information leaves in ordinary attachments, sometimes by mistake and sometimes deliberately. Without inspection on the way out, nobody finds out until it matters.
Filter the volume, catch the targeted, keep a copy of everything
Barracuda covers the full lifecycle of a message: what arrives, what gets through anyway, what leaves, and what you can retrieve afterwards when someone asks.
Cloud-to-cloud backup for Microsoft 365
Microsoft protects its infrastructure, not your data from your own users. Deleted mailboxes, purged items, and ransomware-encrypted files are your responsibility, and a separate backup is the only thing that gets them back.
Advanced spam and malware filtering
The bulk of unwanted mail is stopped at the gateway before delivery, with malware inspection covering attachments and links rather than trusting them by default.
Impersonation and account takeover protection
Watches for the signals of a hijacked internal mailbox and for messages engineered to look like they came from a colleague, supplier, or executive.
Automated incident response
When something malicious was delivered before it was known to be malicious, it is located across every mailbox and removed, instead of relying on staff to report it.
Encryption and data loss prevention
Outbound rules catch sensitive information before it leaves and apply encryption automatically, so protection does not depend on someone remembering.
Archiving and domain fraud protection
Messages are retained for search and compliance, while domain authentication makes it far harder for anyone to send convincing mail using your name.
What most businesses believe is covered, and what actually is
Moving to Microsoft 365 leaves a gap that is easy to miss precisely because everything appears to work. It only becomes visible during an incident, when someone asks to restore a mailbox from four months ago.
What people assume
That the platform includes protection and backup as part of the subscription.
- Mail is filtered well enough by default
- Deleted items can always be recovered later
- The provider keeps a full historical copy
- Ransomware in cloud storage is handled by the platform
What is actually true
The platform guarantees its own availability. Your data and the threats aimed at your people remain yours to manage.
- Targeted impersonation frequently passes default filtering
- Retention windows are limited and pass quietly
- A purged mailbox can be genuinely unrecoverable
- Encrypted files sync to the cloud as changes, not as damage
Quieter inboxes and a shorter list of ways to lose money
People see mail that matters
Removing the overwhelming majority of junk is a productivity gain before it is a security one, and it makes the rare dangerous message stand out rather than blend in.
Invoice and payment scams stop working
Impersonation and domain protection attack the mechanism these frauds depend on, which is a message that convincingly appears to come from someone trusted.
Microsoft 365 becomes recoverable
With an independent backup, a deleted mailbox or an encrypted cloud drive is a restore rather than a permanent loss you discover months later.
Filters are only as good as the rules behind them
Email security is unusually easy to get subtly wrong. Set too loose and the targeted attacks still land. Set too tight and legitimate mail from a customer disappears into quarantine, so somebody widens the rules until the problem goes away and the protection goes with it. Meanwhile domain authentication stays half-configured, quarantine goes unreviewed, and backup runs without anyone confirming a restore works.
Tuned to your mail flow
NYN Impact sets policy against how your business actually communicates, so real customer mail arrives and fraud does not.
Quarantine and alerts reviewed
Someone reads what the system holds and acts on what it flags, rather than leaving detections to accumulate unopened.
Backup proven, not assumed
Retention is set deliberately and restores are tested, so the copy is genuinely there on the day a mailbox has to come back.
Built for businesses living in email
Microsoft 365 organizations
Where the platform is now the backbone of communication and the protection and backup gaps around it have not been addressed.
Finance-exposed businesses
Anyone paying invoices or moving money on emailed instructions, which is precisely the workflow impersonation fraud is built to exploit.
Compliance-driven industries
Where archiving, encryption, and retention are obligations, and being able to produce a message from two years ago is not optional.
The full lifecycle of a message, covered
Barracuda blocks spam and malware at volume, catches the targeted impersonation and account takeover attempts that ordinary filtering misses, inspects what leaves for sensitive data, and keeps an independent backup of Microsoft 365 that the platform itself does not provide. Automated incident response cleans up anything that was delivered before it was known to be dangerous, and archiving keeps the record when someone eventually needs it.
