Why Guardivia
Security and revenue assurance from the same platform, proven at the handset.
Most vendors sell either a firewall, a message centre or a testing service. Guardivia engineers all three, plus the core-network modules around them, so signaling metadata, message content, commercial agreements and real-device evidence are correlated instead of siloed.
What makes Guardivia independent?
Guardivia designs, develops, integrates, maintains and supports its core telecom products through its internal engineering teams. This technology ownership removes dependence on outsourced proprietary product vendors, provides direct access to the engineers responsible for the platform, and enables faster integrations, controlled updates, accountable delivery and SLA-backed operational support.

Security and revenue protection
One inspection environment for SS7 signaling and SMPP traffic
The SMS Signaling and ESME Gateway Firewall correlates content, sender, route, Global Title, velocity, HLR/MNP results and an AI risk score for every message, then applies operator policy: allow, tag, rate-limit, quarantine, block, redirect or reroute.
- Spam and smishing detection
- Sender-ID spoofing and variation
- Grey-route and SIM-box detection
- GT spoofing and home-routing bypass
- OTP flooding and repeated OTP
- A2P/P2P separation and registries
- Revenue dashboards and reconciliation
- SIEM, SNMP, webhooks, audit logs
Traffic intelligence
From raw events to an explainable policy decision
Hawk · Dolphin · Shark
Hawk screens SS7/SIGTRAN SMS signaling and hands message content to the inspection layer. Dolphin and Shark are redundant SMPP, ESME, content, policy and AI engines behind a VRRP-protected service address. All SS7 MO, MT and AT SMS and all external and local ESME traffic pass through the same policy environment before delivery.
- Signaling scope
- SS7/MAP over SIGTRAN, SMS operations
- Application scope
- SMPP v3.4/v5.0, SMPPS/TLS
- Availability
- VRRP, PCC session distribution, health redirection
- AI governance
- Learning mode, proposals, engineer confirmation
Operator messaging infrastructure
Own the message centre and the core around it

Guardivia Operator SMSC
SS7/MAP v1–v3 over SIGTRAN, SMPP v3.4/v5.0, SMPPS/TLS, HTTP/REST and SIP/IMS in one instance. Store-and-forward with MWD and AlertSC retry, HLR lookup, home routing, MNP-aware routing and per-message CDRs.

HLR/HSS/UDM, SS7/SIGTRAN stack and STP, CAMEL Gateway, USSD Gateway, IP-SM-GW, Diameter and DRA, Roaming Suite, plus private LTE/5G integration services. Modules deploy alone or together.
ExploreEvidence-based verdicts
- Confirmed direct route
- Suspected grey route
- Suspected SIM-box termination
- Suspected unauthorised GT route
- Sender ID replaced
- Content or URL modified
- Message-centre changed
- Excessive delivery delay
- Message not received
- Requires signaling correlation
Active route testing
Delivery receipts confirm acceptance. Real devices confirm delivery.
Honeypot SMS Testing and Route Assurance sends identified test messages to trap numbers on real SIMs, compares what was sent with what the handset received, correlates gateway CDRs and firewall decisions, and issues a verdict.
AI intelligence with human governance
AI proposes. Engineers decide.
Guardivia treats AI as controlled operational intelligence. It accelerates analysis and proposes action; authorised engineers decide.
- STEP 1
The platform begins in monitoring and learning mode.
- STEP 2
It establishes traffic baselines per route, sender, account and time of day.
- STEP 3
It analyses content, sender behaviour, route behaviour and emerging patterns.
- STEP 4
It proposes new classifications, rules and thresholds with supporting evidence.
- STEP 5
An AI operational coworker provides daily recommendations during early operation.
- STEP 6
Recommendations may move to a weekly cadence once traffic behaviour stabilises.
- STEP 7
An authorised engineer reviews and confirms enforcement decisions.
- STEP 8
Uncontrolled autonomous blocking is not a feature of any Guardivia product.
Strategic differentiator
Engineered In House. Delivered Without Vendor Dependency.
Guardivia develops and controls its telecom platforms internally, from protocol processing and security intelligence to dashboards, integrations and operational tools. This direct ownership enables faster customisation, accountable delivery, stable releases and SLA-backed support without dependency on outsourced proprietary product vendors.
Complete Technology Ownership
Guardivia controls the architecture, source code, roadmap, updates and lifecycle of its core products.
Direct Operator Integration
Our internal engineers adapt the platform to signaling, messaging, core-network, OSS/BSS, billing, monitoring and regulatory environments.
Faster Response
Direct access to the people who build the technology reduces escalation layers and accelerates troubleshooting, updates and customisation.
Reliable Delivery
Structured testing, controlled releases, performance validation and SLA-backed support protect production stability.
This is a statement about Guardivia's core product technology and engineering lifecycle. Guardivia's platforms run on standard operating systems, commodity server hardware, open standards, cloud infrastructure and open-source components, as any modern telecom software does. The defensible claim is full ownership and control of the core product technology and the engineering lifecycle around it.
