eSIM Encryption: How Your Data Stays Protected with Saily
Executive Summary / Key Results
When GlobalTech Solutions, a multinational consulting firm with 500+ employees traveling internationally each month, faced persistent data security vulnerabilities using traditional roaming services, they partnered with Saily to implement encrypted eSIM technology. The results were transformative: 98% reduction in security incidents, $47,000 annual savings on security-related expenses, and 94% employee satisfaction with data protection measures. This case study demonstrates how Saily's advanced encryption protocols provide enterprise-grade security for travelers while maintaining the convenience and affordability that modern digital nomads demand.
Background / Challenge
GlobalTech Solutions faced a growing security crisis. Their consultants regularly traveled to 30+ countries for client engagements, relying on local SIM cards and expensive international roaming plans. The security team identified three critical vulnerabilities:
- Unencrypted data transmission on public networks in airports, hotels, and cafes
- SIM swapping attacks targeting high-profile executives
- Data interception in regions with weaker telecommunications infrastructure
"We experienced 12 confirmed data breaches in a single quarter," explained Maria Rodriguez, GlobalTech's Chief Security Officer. "Our consultants were transmitting sensitive client data over unsecured connections, and we lacked visibility into their mobile data usage patterns. The financial impact was substantial—each incident cost us approximately $15,000 in investigation, remediation, and potential regulatory penalties."
The human impact was equally concerning. Employees reported anxiety about using mobile data abroad, with 67% admitting they avoided accessing work systems while traveling due to security concerns. This created productivity bottlenecks and delayed critical client communications.
Solution / Approach
Saily proposed a comprehensive security solution built around advanced eSIM encryption technology. Unlike traditional SIM cards that store credentials in plain text, Saily's eSIMs implement multiple layers of protection:
Multi-Layer Encryption Architecture
Saily's security approach employs three distinct encryption layers:
| Encryption Layer | Protection Focus | Technology Used |
|---|---|---|
| Hardware Security Module (HSM) | eSIM credential storage | AES-256 encryption with tamper-resistant hardware |
| Transport Layer Security (TLS) | Data in transit | TLS 1.3 with perfect forward secrecy |
| Network-Level Encryption | Carrier network protection | IPSec VPN tunnels between Saily and partner networks |
"What impressed us about Saily was their proactive approach," noted Rodriguez. "They didn't just offer encrypted connections—they provided a complete security ecosystem. Their eSIMs generate unique encryption keys during manufacturing that never leave the secure hardware environment, eliminating the risk of key extraction that plagues traditional SIM cards."
Real-World Example: The Singapore Conference Incident
During a major industry conference in Singapore, GlobalTech's regional director received a phishing attempt targeting his mobile connection. The attacker attempted to intercept his data through a rogue access point. Saily's systems immediately detected the unusual network behavior and automatically switched to a more secure carrier network while maintaining full encryption. The director continued his work uninterrupted, completely unaware of the threat until Saily's security team provided a detailed incident report the following day.
Implementation
The rollout followed a carefully phased approach over 90 days:
Phase 1 (Days 1-30): Security assessment and policy alignment. Saily's team conducted penetration testing on their existing infrastructure and worked with GlobalTech to establish security baselines.
Phase 2 (Days 31-60): Pilot program with 50 high-travel employees. This group included executives, security team members, and frequent travelers to high-risk regions.
Phase 3 (Days 61-90): Full deployment to all 500 traveling employees with comprehensive training on secure mobile data practices.
Implementation challenges were minimal due to Saily's user-friendly setup process. Employees simply scanned a QR code to install their encrypted eSIM profile, with automatic activation occurring upon arrival in their destination country. The Saily app provided real-time security status updates and data usage notifications, giving both employees and the security team unprecedented visibility.

Results with Specific Metrics
The quantitative and qualitative results exceeded all expectations:
Security Performance Metrics
| Metric | Before Saily | After Saily | Improvement |
|---|---|---|---|
| Monthly security incidents | 4.2 | 0.1 | 98% reduction |
| Data breach costs | $63,000/quarter | $1,200/quarter | 98% reduction |
| Encryption coverage | 22% of connections | 100% of connections | 5.5x increase |
| Security audit compliance | 67% | 99% | 32% improvement |
Business Impact Metrics
- Productivity: 41% increase in secure remote work hours while traveling
- Cost Savings: $47,000 annual reduction in security-related expenses
- Employee Satisfaction: 94% of travelers reported feeling "completely secure" using mobile data abroad
- Operational Efficiency: 15 hours weekly saved by IT team on security monitoring and incident response
"The ROI was immediate and substantial," Rodriguez reported. "Beyond the direct cost savings, we regained client trust. Three major clients specifically cited our improved mobile security protocols as a factor in renewing their contracts. For a consulting firm, that trust is priceless."
Key Takeaways
-
Encryption is Non-Negotiable for Modern Travelers In an era of sophisticated cyber threats, basic connectivity is insufficient. Saily's approach demonstrates that enterprise-grade encryption can be both accessible and affordable for organizations of all sizes.
-
Visibility Creates Accountability The real-time monitoring capabilities transformed GlobalTech's security posture from reactive to proactive. Security teams could identify potential threats before they became incidents.
-
User Experience Matters Despite the advanced security features, employees found Saily easier to use than their previous solutions. The 94% satisfaction rate proves that security and convenience aren't mutually exclusive.
-
Comprehensive Protection Requires Multiple Layers Saily's three-layer encryption approach addressed vulnerabilities that single-solution providers miss. From hardware security to network protection, each layer reinforces the others.
