Always-on traffic monitoring
Every call that enters or leaves your network is inspected in real time. Suspicious patterns are flagged and blocked automatically, without interrupting legitimate traffic.
Voice Fraud Protection
Stay Ahead of Fraudsters
DigitalWell's fraud protection keeps your voice infrastructure secure, blocking threats before they reach your network, your people, or your bills.
Toll fraud, call hijacking, and spoofed numbers are costing businesses real money. The threat is automated, fast, and invisible until the damage is done.
Voice infrastructure is one of the most overlooked attack surfaces in the enterprise. As organisations move from legacy ISDN to SIP, new vulnerabilities open up, and attackers know how to exploit them. Fraudsters probe SIP trunks for weaknesses, hijack call routing to rack up international charges, and spoof caller IDs to impersonate trusted contacts. DigitalWell's fraud protection is built into your voice connectivity from day one. Session Border Controllers (SBCs) act as the security layer for your SIP infrastructure, monitoring, filtering, and blocking malicious traffic in real time before it reaches your network or your bill.
What To Expect From DigitalWell
Fraud blocked at the border
Session Border Controllers act as the security perimeter for your voice network: authenticating traffic, encrypting calls, and preventing unauthorised access before it reaches your PBX or UCaaS platform.
Managed, not monitored
We don't just alert you to a problem and leave you to deal with it. DigitalWell manages your voice security end-to-end, with proactive responses and a single point of accountability.
Business Challenges We Help Solve
You've moved to SIP trunking, but haven't locked it down
SIP opens up your capabilities and your network. We add fraud rules, traffic limits, and authentication from day one.
An unexplained spike in your call costs
Toll fraud can generate thousands in overnight charges. We detect unusual call volumes and shut them down before the bill arrives.
Your number is being spoofed by someone else
Fraudsters impersonate your business using your own caller ID. SBCs validate call identity and block spoofed traffic at the border.
You've had calls routing to international premium numbers you don't recognise
That's IRSF. Automated bots route high-cost calls through your accounts. We stop it at the network level.
Your compliance team is asking about voice security
Voice infrastructure is in scope under DORA and NIS2. We give you the controls and documentation to satisfy auditors.
You're running multiple sites or carriers and have no unified view
Fragmented voice infrastructure creates blind spots. We consolidate security across all sites into one managed service.
How We Work
DigitalWell is built on a foundation of strong engineering, clear accountability, and deep expertise in enterprise voice infrastructure. We've been delivering secure voice connectivity to some of the most demanding organisations for years, and we stand behind our service with real SLAs.
SIP and SBC expertise, deployed in production
We don't resell a third-party security platform and call it managed. Our SBC infrastructure is our own, and our engineers configure and manage it directly.
One contract, voice and security together
If you run your SIP connectivity through DigitalWell, fraud protection is part of the same managed service. No separate vendor, no finger-pointing between suppliers.
Built for Irish and EU compliance requirements
We understand the regulatory landscape - DORA, NIS2, GDPR - and design our voice security posture to help customers meet their obligations, not just tick a box.
Frequently asked questions
What is SIP fraud and how does it differ from traditional phone fraud?
Traditional phone fraud targeted physical lines and hardware. SIP fraud targets IP-based voice infrastructure — probing your SIP trunks for weak authentication, hijacking call routing, or spoofing caller identities. Because SIP runs over the internet, attacks are automated, fast, and can originate from anywhere in the world.
What is a Session Border Controller, and why does my business need one?
A Session Border Controller (SBC) is the security perimeter for your voice network. It sits between your internal systems and the outside world, authenticating every call, encrypting traffic, and blocking unauthorised access before it reaches your PBX or communications platform. Without one, your SIP infrastructure is exposed.
How does toll fraud actually happen — and how quickly can it cost me money?
Attackers use automated bots to scan for SIP accounts with weak credentials. Once they find one, they route large volumes of calls to premium-rate international numbers they control — collecting a share of the revenue while the bill lands with you. It typically happens overnight or over weekends. By Monday morning, the damage is done.
What is caller ID spoofing, and can it damage my business's reputation?
Spoofing allows fraudsters to make calls that appear to come from your number. Your customers receive calls they never initiated — potentially scam calls — with your name on the screen. Beyond the financial risk, the reputational damage can be significant and hard to undo.
Does DigitalWell's fraud protection work with my existing PBX or UCaaS platform?
Yes. Our fraud protection operates at the SIP layer, before traffic reaches your PBX or UCaaS platform. It's compatible with any standards-based system — whether you're running an on-premise PBX, Microsoft Teams Direct Routing, or a hosted communications platform.
Is voice fraud protection covered under DORA or NIS2 requirements?
Voice infrastructure falls within the scope of both DORA and NIS2 as part of your ICT risk surface. Both frameworks require documented controls, active monitoring, and the ability to demonstrate resilience. DigitalWell's managed service provides the controls and audit trail to support your compliance obligations.
What's included in DigitalWell's managed voice security service?
Our service includes SBC deployment and management, real-time traffic monitoring, fraud detection and automated blocking, call encryption, and ongoing incident management. You get a single point of accountability — not a security alert system that leaves you to respond on your own.
Can I add fraud protection to an existing SIP trunk, or do I need to switch providers?
If your SIP connectivity is already with DigitalWell, fraud protection can be added to your existing service. If you're with another provider, we'd typically recommend migrating your SIP to DigitalWell — that way, security is built into the connectivity layer rather than bolted on top.
