Why Us

Why Mobile Operators Need Specialized Cybersecurity Solutions

Mobile operators run some of the most complex, high-volume digital environments in the world. Subscriber authentication, A2P messaging, roaming, network activation, and revenue platforms all generate sensitive data—and each can be misused by fraudsters, compromised accounts, SIM farms, or malicious third parties.

Traditional enterprise security tools do not understand telecom identifiers, carrier-grade traffic, or the flow patterns between subscribers, applications, gateways, and partners.

EntrustedMail delivers cybersecurity solutions for mobile operators designed for:

  • Subscriber identity and account protection
  • A2P and P2P messaging integrity
  • Partner and MVNO oversight
  • Privacy and audit requirements
  • OSS/BSS and operational workflow protection
These protections fit seamlessly into operator environments without interrupting network operations or customer experience.

Top Cybersecurity Risks for Mobile Operators

  • Smishing & Fraudulent Messaging — Malicious SMS/RCS campaigns targeting subscribers with credential theft, malware links, or premium fraud.
  • A2P Grey-Route Abuse — Unmonetized or non-compliant traffic bypassing official channels and draining operator revenue.
  • SIM Swap & Port-Out Fraud — Unauthorized ownership transfers enabling account takeover and interception of MFA codes.
  • Signaling Abuse & Operational Threats — Exploitation of routing, activation flows, or partner connections to disrupt services or harvest subscriber details.
  • Partner & MVNO Misuse — Third-party systems or integrators accessing subscriber data beyond intended scope.
  • Subscriber & Operational Data Exposure — CDRs, activation records, billing files, or identity documents leaked through messaging, email, or cloud storage.
  • Regulatory Non-Compliance — Missing logs, improper retention, or insufficient audit evidence for privacy and telecom regulations.

Frequently Asked Questions

How does EntrustedMail detect and stop smishing, malicious SMS, and fraudulent RCS traffic?

We combine multiple, complementary detection methods so protection is fast and precise:

  • Content inspection & URL analysis — inline scanning of message payloads plus multi-stage URL handling (immediate reputation lookup, then sandbox/execution analysis for suspicious links).
  • Sender reputation & fingerprinting — historical sender behavior, delivery paths, and cryptographic fingerprinting of sending endpoints to spot SIM-boxes, proxy aggregators, or spoofed sources.
  • Behavioural models— machine learning models trained on carrier telemetry detect anomalies in volume, timing, text patterns, and recipient targeting (e.g., sudden bursts to new cohorts).
  • Crowd & threat intelligence—global signals and subscriber reports feed real-time blocklists and campaign groupings so new campaigns are identified faster. What operators see: a decision at the gateway (deliver/quarantine/rewrite to a safe preview/throttle) plus a contextual alert with full evidence (message sample, sender chain, URL verdict).
EntrustedMail is engineered for carrier-scale, low-latency processing:
  • Inline, optimized pipelines process most classification checks in-stream (micro- to millisecond ranges) so normal traffic is not perceptibly delayed.
  • Fast-path & adaptive routing: Trusted, whitelisted senders can be placed on a fast-path; ambiguous messages are escalated to deeper analysis asynchronously or via safe-hold/preview modes.
  • Performance testing & SLAs: Before production roll-out we perform load tests using your gateway throughput profile and publish expected latency impact and capacity recommendations.
  • Operators retain control: you can choose stricter real-time blocking for high-risk segments or more permissive handling for marketing traffic where throughput is critical.
We make non-compliant traffic visible and actionable:
  • Source attribution & path analysis — map each message to its ingress path, sender ID, CPaaS provider, or SIM-farm fingerprint.
  • Traffic classification API — provides a real-time verdict at the gateway to block, throttle, or route traffic into approved channels.
  • Sender reconciliation & reporting — nightly reconciliation reports list top grey-route sources, suspected aggregators, and estimated billable message volume lost.
  • Enforcement options — automated throttling, sender blacklisting, routing to billing-enabled paths, or escalation to commercial teams for remediation and monetization.
  • Outcome: faster identification of leakage, enforcement of monetized routes, and measurable increases in billable A2P traffic.
EntrustedMail’s DLP is telecom-aware:
  • Pattern + ML classification — regex and model-based recognition for MSISDN, IMSI, IMEI, IMSI/IMEI pairings, CDR formats, billing spreadsheets, and provisioning exports.
  • Contextual policy actions — depending on sensitivity and destination, the system can encrypt, quarantine, redact identifiers, require additional approvals, or block the transfer.
  • End-to-end controls — apply access controls, tokenized previews, or time-limited share links for sensitive artifacts stored in cloud drives.
  • Audit & chain of custody — every action (detection, enforcement, user override) is logged with a tamper-evident record suitable for audits.
Deployment follows a phased, low-risk approach: discovery → pilot → staged rollout → tuning → full-scale operations. Typical steps:
  • Discovery (1–2 weeks): ingest topology, messaging volumes, OSS/BSS endpoints, and ticketing systems.
  • Pilot (days to weeks): integrate with a gateway or a non-production feed, validate detection rules, and tune ML thresholds.
  • Staged rollout (1–4 weeks): roll protection out to selected traffic slices (e.g., short codes, long codes, or particular origination ranges).
  • Full rollout & tuning (weeks): expand protections, optimize false-positive handling, and operationalize reporting. Time to live depends on operator scale and integration depth; pilots are designed to show measurable protection quickly while minimizing disruption.
We provide continuous oversight across partner interfaces:
  • API & connector monitoring — ingest logs from MVNO portals, CPaaS APIs, or interconnect hubs to monitor message origination, OAuth activity, and permission changes.
  • Behavioral baselines per entity — build a normal profile for each MVNO/partner and alert on deviations (excessive volume, unusual destinations, new payload types).
  • Access governance—flag permission creep (e.g., partners granted file export rights) and integrate with IAM to revoke or adjust privileges.
  • Partner scorecards — periodic reports that quantify partner risk, compliance posture, and actionable remediation steps.
Detection relies on multi-signal correlation and integration with provisioning systems:
  • Transactional signal analysis — monitor port requests, SIM change submissions, and activation events across NOC/provisioning systems for velocity and pattern anomalies.
  • Device/context checks — detect abnormal device churn (IMEI changes), location mismatches, and impossible travel signals.
  • Risk scoring & step-up authentication — suspicious requests trigger automated workflows: require additional verification, hold the request for manual review, or require multi-factor confirmation.
  • Playbook integration — tie alerts into ticketing (ServiceNow/Zendesk) with suggested remediation steps and audit records for dispute handling.
We combine UEBA, DLP, and workflow automation:
  • User & entity baselining — create behavioral baselines by role and function (retail agent vs. NOC engineer) to detect deviations such as bulk downloads or off-hours exports.
  • Context-aware DLP — monitor attachments, ticket notes, and cloud transfers for sensitive telemetry; automatically mask or quarantine where appropriate.
  • Automated remediation — suspicious events can trigger automated steps (revoke access tokens, suspend sharing links) and create incident tickets with full forensic detail.
  • Staff nudges & training feeds — inline, educational prompts help staff correct risky behavior in real time without creating excessive friction.

False-positive management is core to operational acceptability:

  • Granular exception policies — create role-, sender-, or flow-specific allowlists and temporary exceptions with automatic expiry.
  • Feedback loop & human review — analysts can mark events as false positives; the system learns from these actions to reduce repeat misclassifications.
  • Staged enforcement—start with monitoring only, then notify, then quarantine, and finally block—giving teams time to tune thresholds.
  • Change governance — all exceptions are recorded, time-bound, and visible to compliance teams to avoid uncontrolled whitelisting.
We deliver audit-ready artifacts that align with telecom/regulatory needs:
  • Tamper-evident logs with timestamps, decision rationale, and attached message samples.
  • Retention & legal-hold exports for requested timeframes in common formats (CSV, JSON, encrypted archives).
  • Policy-activity reports showing what enforcement actions were taken and by which rule.
  • Incident timelines and chain-of-custody packages suitable for regulator review or forensic investigation.
