Smarter Scam Defense for Your Mobile Users

No. It adds enterprise-level authentication on top of it.

Typically days using our REST API or SIP configuration.

No. Protection happens inside the carrier network.

SENTRY and INFORM are designed to complement each other. SENTRY ensures that only your legitimate outbound calls are delivered by blocking any spoofed calls made on your business numbers. INFORM then brands those authenticated calls with your business name, logo, and call reason so your customers know exactly who's calling and why. Together, they create a complete trust loop: fraudulent calls never reach your customers, and every real call arrives with your brand front and center. You can also choose which calling programs receive INFORM branding, SENTRY protection, or both — giving you full control over how each line of business is handled.

SENTRY integrates with your existing phone system through a simple API or SIP integration. When you initiate an outbound call, your system sends the caller and recipient details to First Orion. First Orion generates a unique authentication key with a time limit for that specific call and sends it to the mobile carrier. When the call hits the carrier network, the carrier checks for a matching valid key. If it matches, the call goes through normally. If there's no key — meaning someone else is trying to use your number — the call is blocked and never reaches the recipient. The entire process happens in real time with no impact on your legitimate call flow.

SENTRY is First Orion's call blocking solution that prevents scammers from using your business phone numbers to make fraudulent calls. When bad actors spoof your number, your customers receive calls that appear to come from your business — damaging trust and putting your brand reputation at risk. SENTRY stops this by authenticating every outbound call through a unique key system. Before your call is placed, First Orion generates a time-limited key and shares it with the carrier network. When the call reaches the carrier, it checks for that key — legitimate calls are delivered, and anything without a valid key is blocked before it ever reaches your customer. SENTRY works across all major U.S. carriers and is especially critical for industries frequently targeted by impersonation fraud, including financial services, healthcare, and insurance.

AFFIRM uses validation calls to observe how business calls are displayed on mobile devices and surfaces those insights in the Customer Portal.

Both can be tagged by carriers, allowing recipients to decide whether to answer.
