Enterprise-grade IoT security features to look for in 2026

The IoT security landscape has shifted from basic password protection to layered, architecture-level defenses. From mobile POS devices to connected utility meters and beyond, if you are evaluating IoT connectivity or platform providers, here are the security capabilities that matter most right now.

Zero Trust architecture for IoT

The traditional network perimeter does not exist for IoT. Devices operate in the field, on public networks, and in environments you do not fully control. Zero Trust assumes no device, user, or connection is trusted by default. Every request is verified, every connection is authenticated, and access is granted on the narrowest basis possible.

For IoT specifically, Zero Trust means device-level authentication (not just network-level), continuous validation of device identity, and microsegmentation that isolates each device from every other device on the network.

Post-quantum cryptography readiness

Quantum computing is not a theoretical concern for long-lived IoT deployments. Devices installed in 2026 may still be in the field in 2036, and the cryptographic standards protecting their data today may be vulnerable by then. The National Institute of Standards and Technology (NIST) finalized its first post-quantum cryptographic standards in 2024, and forward-thinking IoT providers are already planning migration paths.

When evaluating providers, ask whether their encryption layers can be updated over the air and whether they are tracking NIST's post-quantum migration timelines.

EU Cyber Resilience Act compliance

The EU Cyber Resilience Act, which takes effect in stages through 2027, sets mandatory cybersecurity requirements for all products with digital elements sold in the EU. For IoT devices, this means mandatory vulnerability disclosure, security update support for the product's expected lifetime, and secure-by-default configurations.

If you sell connected products in the EU, or plan to, your connectivity provider's security architecture needs to support these requirements.

NIST IoT security frameworks

NIST's Cybersecurity Framework (CSF) and its IoT-specific guidelines (NISTIR 8259 series) give teams a practical blueprint for securing connected devices. The strongest IoT security programs map their controls to these frameworks. Ask your provider how their architecture aligns with NIST CSF categories: Identify, Protect, Detect, Respond, and Recover.

How Hologram secures global IoT fleets

Hologram's security architecture starts at the network level and extends to every SIM and every device in your fleet.

Software-defined network (SDN) security

Hologram's connectivity runs through a proprietary software-defined network. This gives Hologram direct control over traffic routing, access policies, and isolation rules, without depending on a single carrier's security posture. Every data session is authenticated and routed through Hologram's secure core before reaching your backend.

Network isolation by default

Every Hologram device is isolated from the public internet and from every other device on the network. Out of the box, there is no way for an external actor to reach your device, and no way for one compromised device to pivot to another. You have to explicitly open connections, which inverts the typical IoT security model from "lock down what you can" to "nothing is open unless you choose to open it."

Zero-access architecture

Hologram's zero-access model means devices connect outbound to your defined endpoints, but are not addressable from outside the network. This is not a firewall rule you configure. It is how the network works at the architecture level.

IMEI locking

Tie each SIM to a specific device's International Mobile Equipment Identity (IMEI). If the SIM is moved to a different device, connectivity is automatically blocked. This prevents SIM cloning, SIM swapping, and unauthorized device access.

Real-time anomaly detection

Hologram monitors data usage patterns across your fleet and surfaces anomalies: unexpected usage spikes, devices connecting from unusual locations, or sudden changes in data patterns. These signals can trigger automated alerts or policy actions through the dashboard or API.

PCI and HIPAA compliance support

Hologram's private APN and VPN tunneling capabilities create the encrypted, isolated data paths that PCI DSS and HIPAA require. For teams processing payment data or protected health information over cellular, Hologram's architecture meets the connectivity-layer requirements of these frameworks.

Enterprise security checklist

Use this checklist when evaluating IoT connectivity providers for enterprise deployments.

Network-level security

• Private APN support: dedicated data path between devices and your backend
• VPN tunneling (IPsec): encrypted tunnel from the cellular network to your endpoints
• Network segmentation: devices isolated from each other and from the public internet
• IMSI monitoring: alerts for SIM identity changes that could indicate cloning or swapping

Device-level security

• IMEI locking: SIM tied to a specific device, blocked if moved
• IoT SAFE support: SIM-based hardware root of trust for device authentication
• Over-the-air credential rotation: ability to update certificates and keys remotely
• Secure boot and firmware validation: verification that device software has not been tampered with

Operational security

• Real-time anomaly detection: automated alerts for unusual usage or connection patterns
• Audit logging: complete record of device events, policy changes, and administrative actions
• Role-based access control: granular permissions for team members managing the fleet
• Incident response integration: webhooks and API support for feeding events into your security operations center (SOC)

Compliance and governance

• PCI DSS alignment: for payment-related IoT devices
• HIPAA alignment: for healthcare-related IoT devices
• EU Cyber Resilience Act readiness: for devices sold in the EU
• NIST CSF mapping: controls aligned to Identify, Protect, Detect, Respond, and Recover
