Cape offers a specialized version of our product designed for highly targeted individuals—Cape Obscura.

We partner with top security professionals to protect you, your clients, executives, and employees' identities while keeping locations hidden.

We are the only cloud-based mobile carrier built with privacy and security from the core.

How CAPE PROTECTS YOU

  • Privacy and Anonymity

    Cape collects only the essentials—no names, social security numbers, or birthdates. Call metadata, like location data or call logs, is stored or not at all. For details, check our .

  • Security

    Cape is the only privacy and security-focused cellular carrier running all traffic through our own mobile core. This gives us control of subscriber authentication, how calls and SMS are routed, and what information is shared from phones to the network.

  • SIM Swap Protection

    SIM swapping is used by bad actors to steal your phone number and access your financial and social media accounts. Cape protects against SIM swaps using modern account authentication protocols. You, and only you, can transfer your phone number using a 24-word private key, which Cape does not ever store or read.

  • Location Obfuscation

    Cape Obscura works like any other high-end smartphone, but allows you to automatically change device identifiers. This thwarts location tracking using AdTech or even more advanced surveillance tools like IMSI catchers.

  • Ad Profiling Disruption

    Our pre-configured Android device automatically rotates the subscriber's AdID, a unique identifier used by apps and websites to track your behavior, impeding their ability to profile and target you.

TESTIMONIALS

  • "If you’re not using Cape, you’re not taking telecom cyberattacks seriously enough. Cape rotates your IMEI number and other unique identifiers. You can automatically geofence certain locations and assign yourself a fake persona. It’s an ultra-secure phone service for mere mortals like me."

    Nicole Perlroth

    Bestselling author of This is How They Tell Me the World Ends

  • “Our cellular networks are full of threats that are notoriously hard to detect and defend against. Cape changes the equation for defenders by giving them the technology and tools necessary to thwart sophisticated attacks across the cellular, mobile, and adtech domains.”

    Dane Stuckey

    CISO at OpenAI

  • “Most privacy solutions—like specialized apps or burner phones—focus primarily on app and device-level threats. Yet, some of the most serious vulnerabilities stem from network-level weaknesses. By addressing both device and network security, Cape offers a broader layer of protection against sophisticated threats.“

    Andy Makridis

    Former COO of CIA

  • “The risk of attacks on our cellular networks are far-reaching, severe, and growing. And due to the obfuscated relations between telecommunications carriers across the globe there is little we can do on our own to manage the risk. Thankfully, Cape goes far beyond VPNs and app-level protections to deliver a product that proves that cellular connectivity doesn’t have to come with sacrificing security.”

    Joe Sullivan

    Former CSO at Cloudflare, Facebook, and Uber

  • “Our phones know everything about us, yet we’ve been stuck using carriers that sell or leak our data. It’s about time we had a more complete privacy solution for our phones!”

    Brian Stoner

    Former VP of Product at DuckDuckGo

  • “As an organization, we're concerned with keeping vulnerable individuals safe from dedicated and malicious attackers such as stalkers and abusers. Cape's technology defends against sophisticated threats, and those solutions will also help keep our clients safer.”

    Chris Cox

    Director of Operation Safe Escape

Protected by Cape.

Cape stands in support of vulnerable and at-risk individuals like domestic abuse survivors, activists, whistleblowers, and journalists.
