CasVPN Overview September 2021

Warning! CasVPN’s site and apps are so glitchy that errors prevented me from subscribing to the paid version. For this review, I was restricted to a limited 7-day free trial (which isn’t even advertised on CasVPN’s website!).

With a rating of almost 4 out of 5 stars on Google Play and positive reviews on other blogs, I expected CasVPN would work well. But my testing proved otherwise. The free trial version offers a few unreliable servers, inconsistent speeds, and unusable privacy features. Unfortunately, the full version isn’t any better — it includes a small server network (with 150+ servers vs. Surfshark’s 3,200+) and unreliable connections. It also doesn’t unblock streaming sites, protect you while torrenting, or work in China!

Given these limitations, I expected it would at least be cheap — so I was surprised by its expensive prices! If you manage to get the site working, you could use its free trial or one of its pricey plans. But I’d recommend you avoid CasVPN altogether and instead try an affordable top-tier VPN like Surfshark for free for 30 days. It offers superior speeds, access to streaming, and military-grade security for less than the price of a cup of coffee.

Don’t Have Time? Here’s a 1-Minute Summary

  • Inconsistent server speeds. My connections were never reliable, sometimes giving me both fast and slow speeds. Its servers also don’t work with streaming or torrenting. Check out my speed tests.
  • Decent privacy policy, but you can’t use the app’s privacy features. Even though the privacy policy sounds safe, critical safety functions in the app don’t work and it hasn’t been independently audited. See my privacy analysis.
  • Website and apps are so glitchy that I couldn’t subscribe to the service. I kept getting errors in the app and the website’s payment page didn’t work at all. Jump to my user experience testing.
  • Lackluster support and a deceitful money-back guarantee. Its support never even responded to me and the money-back guarantee is voided when you exceed 3GB of data. Read my review of CasVPN support.
  • Expensive and poor value. CasVPN has pricier plans than many superior competitors, making it a very poor value. Find out my final verdict.


CasVPN Isn’t as Fast as the Competition

CasVPN doesn’t have an advanced enough server network to offer fast speeds like its larger competitors. With servers in Canada, Australia, and Paris, my speeds averaged just over 30Mbps. That was a huge 71% percent drop from my baseline speed of 103Mbps! I was disappointed that most of CasVPN’s servers caused buffering and long loading times when I tried browsing or watching YouTube videos.

I experienced significant lag when I connected to CasVPN

With only 4 servers available to free trial users, CasVPN’s options get crowded quickly and frequently slow down. You can get much faster servers (that actually work reliably) at a similar price with a top VPN like Surfshark. But don’t take my word for it — I recommend you try Surfshark’s faster speeds for free for 30 days so you can see how it works with streaming, gaming, torrenting, and video chat.

Why Most Speed Tests are Pointless & How We Correctly Test VPN Speeds

Speed determines how fast content uploads, so if you're torrenting or streaming, you want the speed to be somewhat identical to your regular internet speed. Since a VPN encrypts your data, it usually takes a bit longer to send your data back and forth, which can slow down your connection. However, if your ISP deliberately slows down your connection (also known as throttling) a VPN might increase your internet speed. Testing a VPN is somewhat pointless because new servers pop up and affect speed. Your speed can also differ according to your location, so your speed test might not match ours. Having said that, we tested the speed in numerous locations to provide you with the average.


Server Network — Decent Country Coverage, But Unreliable

With about 150 servers, CasVPN has a very limited networktop-tier VPNs like ExpressVPN have over 3,000 servers in 94+ countries to choose from. In spite of the limited network, I was impressed that it has servers in almost 60 countries. Coverage in Africa is still limited to just one server, but the variety of locations is still enough to compete with some of the biggest names in the industry.

Unfortunately, the wide global network is ruined by the fact that the app often fails to connect. The free trial version only gives you 4 servers to try: Australia, Belgium, France, and Canada. Even with only those options, I frequently had connection errors and couldn’t use the VPN at all. During my tests, I only connected instantly to the server in Australia once, and the server in Belgium never worked. The others stalled indefinitely while connecting and only worked after I retried 5 or 6 times.

My connections on CasVPN’s server network were extremely unreliable

Even if you have better luck connecting to CasVPN’s network, not even the paid version has servers that can unblock streaming sites like Netflix or protect you while torrenting. Plus, its servers definitely don’t work if you’re in a location with tough censorship like the UAE and China. These limitations make it weak compared to other providers in the price range, which have far more servers for a similar cost.

Security — Surprisingly Strong Security for a Small VPN

CasVPN’s security is stronger than most VPNs of similar size, but it doesn’t measure up to the security offerings of top services like NordVPN. It uses 256-bit military-grade encryption to keep your data hidden, which I tested using a DNS leak detector. This would expose whether my data was leaking to my internet provider, government, or any other third-parties. I was pleased the test detected 6 different Australian servers. Since I’m located in the US, this proved that CasVPN’s encryption successfully hid private data like my real identity and location.

To prevent threats from infecting your devices and compromising your security, CasVPN uses an integrated NAT firewall. This keeps you safer on public WiFi networks, which hackers love to exploit because they’re the easiest networks for them to steal your data.

I was impressed that CasVPN includes an intrusion protection system to block spyware, malware, and other malicious software hackers use to steal your data or take over your device. Very few small VPN providers offer this security bonus, but for a similar price you can get a more powerful VPN with even better malware blockers like NordVPN.

Privacy — Good Privacy Policy, But I Couldn’t Use the Kill Switch

CasVPN’s privacy policy clearly states that it doesn’t share or collect logs on any of your data. It only stores as much information as is needed to collect payment using credit cards or PayPal. This policy reassured me, but I would feel safer if it had been audited by third-parties to ensure it’s really being followed. For example, the safest services like NordVPN have even published independent audits of their privacy policies to give users greater peace of mind.

CasVPN has a solid privacy policy, claiming they don’t record or store any of your data

That said, the app still has privacy problems of its own. CasVPN’s website claims the app has an internet kill switch, which is meant to protect your privacy even if you lose the VPN connection — but it isn’t on by default. Worse yet, I couldn’t access the settings menu to find and activate it. Since its servers occasionally lose their connection, your personal data could be exposed if you can’t figure out how to turn the kill switch on (like me).

Does CasVPN Work in China? The Website Says Yes, But I Wouldn’t Trust It

CasVPN claims to work in China, but I never heard back after emailing customer service to confirm the claim. Since CasVPN doesn’t have a working kill switch and has unreliable connections, I definitely would not feel safe using it in China. Plus, after 6+ years working in cybersecurity, I’ve found that there are only a few VPNs that can bypass Chinese firewalls and keep your data private. I would be really surprised if CasVPN actually works in heavily-censored countries like China!

Simultaneous Device Connections — Supports Up to 3 Devices at Once

CasVPN supports up to 3 of your devices at once — but I was disappointed with this offering since similar-priced or cheaper VPNs work with many more devices. It also only works on 5 device types: macOS, Windows, iOS, Android, and Linux. While it works on these operating systems, it’s far from being the top Windows VPN or the best service for Mac or mobile. Plus, if you want to connect your gaming systems or Smart TVs, it won’t work at all.

You can connect unlimited simultaneous devices to Surfshark, including more device types and operating systems (including PS4 and Firefox). It costs less per month with its 2-year plan and you can even try Surfshark on unlimited devices for free for 30 days with its money-back guarantee. This gives you plenty of time to make sure it works on all the devices you own.

Ease of Set-Up & Installation — Glitchy Apps and Confusing Installation, But There’s a Free Trial (If You Can Find It)

CasVPN’s website is so glitchy, I wasn’t even able to subscribe to the service. No matter which payment option or subscription tier I tried, I kept getting error messages when I tried to pay. When I wasn’t able to pay with a credit card, I then tried the PayPal method. After entering my PayPal email and password, I got an error:

This merchant isn’t able to accept payments at this time. Please try again later or return to the merchant and choose another way to pay.

I decided to install CasVPN without paying so I could test the installation process. There is some supplemental software that you have to install at the same time to make the VPN work. Since this wasn’t explained beforehand, it caught me by surprise. However, it was easy to finish the process using all the default options.

I was surprised to see additional installation screens during setup that weren’t explained

When I opened CasVPN for the first time, I discovered how to access an unadvertised free trial version. After downloading and installing the app without paying, you’ll see an initial login screen on startup with a button reading “No account? Sign up free.” I clicked the button and made an account, and then was able to log into the app with my new credentials to start a hidden 7-day free trial.

Even if you manage to complete your subscription or access the free trial, the apps are extremely glitchy. On every version of the app (both mobile and desktop), I often couldn’t connect to servers. I randomly disconnected every few hours and found many buttons in the options menu that didn’t work at all. For example, there are large “Purpose” and “Protocol” buttons ⁠— but both lead to an error message when clicked. The “Settings,” “Share,” and “Rate” buttons didn’t do anything at all.

CasVPN’s menus give you lots of errors and broken buttons

For a VPN that hardly ever glitches or disconnects me randomly, I’ve never encountered any major glitches after years of using ExpressVPN. Plus it’s easy to set up and use with tons of lightning-fast servers and customization options.


I wasn’t happy with CasVPN’s support options as its live chat response time is inconsistent ⁠— if they ever respond at all. After telling a live chat rep that I encountered errors while trying to pay for the service, he got back to me within a few minutes and told me he would look into the problem. But 3 weeks and 2 follow-ups later, he still had not resolved the problem.

CasVPN also offers a support ticket system in its online user portal. I logged into my account and filed a support ticket, but even after 2 weeks of waiting I never got a response. Other than its live chat and support tickets, an online email form is the only other clear way to contact CasVPN ⁠— but I found the email support page difficult to use. It requires that you attach a screenshot of technical errors. But for questions that don’t require screenshots, it adds an unnecessary step that you can’t skip.

CasVPN’s email support is complicated and hard to reach

To bypass the need to attach a file, I tried to find a direct email address elsewhere on CasVPN’s website. No matter where I looked, I couldn’t find one. After sending my support request with a blank image file attached, I got an automated email from [email protected] saying my message was received and someone would get back to me as soon as possible. After not hearing back for a week, I followed up using the same email address — but even after 3 weeks of waiting I haven’t heard anything.

I prefer VPNs that have reliable email and 24/7 live chat support like Surfshark. That way if you have a problem, you can get an answer right away. Thorough testing showed me that Surfshark offers lightning-fast, knowledgeable customer support.

How We Test Customer Support and Why Should You Care

We personally test the customer support team of every VPN we review. This means asking technical question through the live chat feature (where applicable) and measuring the response time for email questions. Whether you need to connect to a specific server, change your security protocol, or configure a VPN on your router, finding a VPN with quality customer support should be important to you.


Payment Options

CasVPN claims to allow payments using credit cards or PayPal, but neither payment method worked for me when I tried to subscribe. I tried 10 times over the course of 3 weeks — no matter which payment method or package I tried to buy, I got error messages and couldn’t complete my purchase.

No matter which payment method or subscription I tried, I wasn’t able to buy CasVPN

Even if I had been able to buy it, I can already tell from its features and pricing that other VPNs offer a better value. With more servers, reliable apps, and the ability to unblock major streaming sites like Netflix, you can get better features from Surfshark at a lower price.

Money-Back Guarantee

CasVPN only offers a 7-day money-back guarantee. It’s not as generous as most premium VPNs, which give you at least 30 days to try them risk-free. It’s also not unconditional ⁠— CasVPN’s Terms of Use states it’s voided if you exceed 3GB of data. Since this isn’t mentioned anywhere else, I thought this was a bit misleading. Plus, 3GB also isn’t very much and could be exceeded after watching just 1 or 2 movies in HD.

Although CasVPN has a free trial, I thought it was odd that it isn’t advertised anywhere and is hidden in its app’s “Create an account” option. This free trial also doesn’t work very well. Overall, I had a far better experience with ExpressVPN. You can try it free for 30 days and get a no-questions-asked refund (even if you used tons of data!). When I tried it, I got my money back in only 5 days.

CasVPN offers the following plans

Final Verdict

I don’t recommend CasVPN — it offers glitchy apps, a website that won’t let you buy the product, and unreliable servers. Even if it were less expensive, there are still better options on the market. At its current price, you save money and enjoy superior features from providers like Surfshark. While its security is decent, there’s no point in trying to protect yourself with an app that barely works!

Common CasVPN FAQs

? Is CasVPN any good?

CasVPN isn’t the best VPN on the market ⁠— it’s slow, has lots of errors, and offers a small and unreliable server network. The worst part is that some of its plans are even more expensive than top-tier competitors. As a better alternative, you can try Surfshark’s fast 3,200+ servers for free for 30 days. It offers more affordable plans and better features, so it’s a far better value.

? Is there a free version of CasVPN?

CasVPN has a 7-day free trial, but it isn’t advertised anywhere on the website. To unlock the trial, simply download the VPN without paying for the service. Then, click the button at the bottom of the app’s login screen to create an account. Once you click the confirmation email, you can log in with your new password to use it risk-free for 1 week.

Though accessing CasVPN’s free trial is straightforward, it’s not as generous as other top-tier providers’ offerings. For example, you can use Surfshark’s superior service for free for 30 days.

? Is CasVPN a safe VPN option?

Even though CasVPN uses powerful encryption, it doesn’t have a reliable kill switch or independently-audited security policies. This means that any time you lose your connection (which I did often with CasVPN’s glitchy apps), your private data will be exposed to prying eyes like your internet provider, government, and even cybercriminals. Plus, the lack of an independent audit means you’ll have to take CasVPN’s policies at face-value.

For a more secure alternative, you can try NordVPN’s superior security features risk-free for 30 days. It keeps you safer online with a reliable kill switch and an independently-verified no-logs policy to keep your data private.
