Short version: Mullvad (Swedish, since 2009) is the privacy-purist VPN — anonymous 16-digit account, €5 flat pricing, PQ-WireGuard quantum-resistance, DAITA traffic-analysis defense, fully open-source. The 2023 Swedish police raid where they had nothing to hand over is the real-world stress test. Casper is the unified consumer privacy stack — VPN + Pi-hole DNS filtering + ML zero-day phishing detection in one app. Below: where each materially wins.
Yes Partial / limited No
| Feature | Casper's Cloak | Mullvad VPN |
|---|---|---|
| Encrypted VPN tunnel (WireGuard / OpenVPN) | ||
| Both offer WireGuard + OpenVPN. Mullvad also ships PQ-WireGuard (post-quantum-resistant key exchange, launched 2023) — defends against 'harvest now, decrypt later' threat models. Casper runs standard WireGuard. | ||
| Anonymous account model (no email, no name) | ||
| Mullvad's signature feature: at signup, you get a random 16-digit account number. No email, name, or PII required. Payment in cash (mail an envelope), crypto, Swish, or bank transfer. As anonymous as VPN accounts get. Casper requires a standard account with email. | ||
| Flat pricing — no tiers, no plan-length discounts | ||
| Mullvad: €5/month flat, regardless of plan length or feature set. Every customer pays the same. Casper has tiered subscriptions; see /subscriptions for current pricing. | ||
| Verified no-log policy with independent audit | ||
| Mullvad has commissioned Cure53 audits since 2018 and Assured AB audits more recently — one of the longest audit histories in the industry. The 2023 Swedish police raid (where Mullvad genuinely had nothing to hand over because they don't log) is the real-world stress test most VPN no-log policies never face. Casper publishes audit reports too, shorter track record. | ||
| Network-level ad blocking (every app) | ||
| Mullvad offers DNS content blocking (ads, trackers, malware, social media, gambling, adult content — toggle-able) via custom DNS servers. The blocklists are conservative (less aggressive than Pi-hole). Casper runs a Pi-hole instance per user — larger and more aggressive blocklists (StevenBlack, OISD, AdGuard DNS, plus our own list). See /compare/pi-hole. | ||
| Network-level tracker blocking | ||
| Both block trackers at the DNS layer when connected. Coverage depth differs — Casper's Pi-hole engine has broader CNAME-cloaked tracker coverage. | ||
| AI / ML-based zero-day phishing detection | ||
| Mullvad's DNS content blocking is static-list-based. Casper layers an ML model that scores domains in real time, catching newly-registered phishing infrastructure before it hits any static blocklist. Static-list vs static-list + ML. | ||
| CNAME-cloaked tracker resolution | ||
| Casper's Pi-hole engine resolves CNAME-cloaked trackers (the tracker pretends to be a first-party domain). Mullvad's DNS handles common cases but coverage is narrower. | ||
| DAITA — Defense Against AI-guided Traffic Analysis | ||
| Mullvad's flagship 2024 feature — pads and obfuscates packet timing/sizes so that traffic-analysis classifiers (ML models trained to identify websites by traffic patterns) can't fingerprint your browsing through the encrypted tunnel. Niche but unique in the commercial VPN market. Casper doesn't ship traffic-analysis defense. | ||
| Multihop (route through two VPN servers) | ||
| Mullvad supports multihop — your traffic exits through one country and routes via another, defense against compromised exit servers. Similar to ProtonVPN's Secure Core. Casper doesn't ship multi-hop. | ||
| Quantum-resistant tunnels (PQ-WireGuard) | ||
| Mullvad's post-quantum-resistant WireGuard implementation defends against 'harvest now, decrypt later' attacks where adversaries collect encrypted traffic today to decrypt with future quantum computers. Mullvad is the only major commercial VPN shipping this today. | ||
| All clients fully open-source | ||
| Every Mullvad client (Windows, macOS, Linux, iOS, Android) is open-source on GitHub, including the mobile apps. The VPN daemon, the UI, the build system. Casper's clients are not fully open-source today. | ||
| Streaming-region bypass (Netflix UK from US, etc.) | ||
| Mullvad explicitly does NOT optimize for streaming bypass — they say so on their site, and treat it as an arms race they decline to enter. If your primary use case is streaming, look at NordVPN or ExpressVPN. Casper's VPN supports region selection but isn't tuned for streaming evasion either. | ||
| Free tier | ||
| Neither offers a free tier. Mullvad offers a 30-day money-back guarantee. Casper offers a trial period — see /subscriptions for current terms. See also /blog/free-vpn-vs-paid-2026 for the honest reasoning behind paid-only models. | ||
| Server fleet (country count) | ||
| Mullvad: ~700 servers across ~50 countries — deliberately compact, no inflated 'virtual server' counts. Casper: smaller, optimized for North America + Europe + APAC. Both are smaller than ProtonVPN (~110 countries) or NordVPN (~60 countries with thousands of servers). | ||
| Native iOS / macOS / Android apps with full features | ||
| Per-app split-tunneling on mobile | ||
| Casper supports per-app routing on iOS/Android/macOS (banking app bypasses VPN, browsing tunnels). Mullvad supports split-tunneling fully on desktop; mobile coverage is more limited. | ||
| Single-app unified UX (VPN + DNS + threat detection in one) | ||
| Casper's single app includes VPN + Pi-hole DNS + ML threat detection. Mullvad's app includes VPN + DNS content blocking toggles — but the threat detection layer is static-list, not ML, and the configuration is more power-user oriented. | ||
| Mullvad Browser (Tor Project collaboration) | ||
| Mullvad shipped Mullvad Browser in 2023 in collaboration with the Tor Project — a hardened Firefox-based browser without the Tor network (uses your VPN tunnel instead). Anti-fingerprinting, anti-tracking, configured for privacy by default. Available standalone, not tied to a Mullvad subscription. Casper doesn't ship a browser. | ||
| P2P / torrenting support | ||
| Both support P2P. Note: Mullvad removed port forwarding in 2023 (was being abused); P2P still works but DHT seeding effectiveness is reduced. | ||
| Operational history | ||
| Mullvad: founded 2009, owned by Amagicom AB, Swedish — 16+ years of operational history. Casper is newer. | ||
Two genuinely different philosophies of privacy product. Here's the cleanest decision criteria.
Real questions buyers ask before choosing.
VPN + Pi-hole DNS filtering + ML threat detection in a single subscription. Try Casper and decide for yourself whether the unification is worth more than Mullvad's privacy-purist depth.
