SlickVPN Review 2025: Serious Security Risks and Red Flags Found

As a cyber security consultant with over 12 years specializing in cloud data security, I‘ve analyzed and tested countless VPNs. The virtual private network industry is highly competitive, with established players building trust by transparently sharing their security practices and inviting independent audits.

So when I came across SlickVPN, a small provider I hadn‘t heard of before, I was intrigued to investigate what they offered. However, after attempting to test SlickVPN for this review, I quickly uncovered several serious red flags that I cannot ignore as a security professional.

Unverified Software Blocked by Apple

One of the most concerning issues I discovered is that the SlickVPN app is blocked from installing on macOS. When I tried to download it on my MacBook Pro running macOS Ventura 13.2, I received an error message stating: "SlickVPN can‘t be opened because Apple cannot check it for malicious software."

This occurs when the developer has not submitted their software to Apple for verification using a Developer ID. Most legitimate software, especially products entrusted to secure your data like VPNs, will go through this vetting process. The fact that SlickVPN did not raises major questions about the trustworthiness and intentions of the app.

I would strongly warn against attempting to install SlickVPN on a Windows PC as well. Microsoft‘s security model allows unverified software more leeway than Apple‘s walled garden approach. An untrusted app could potentially infect your system with malware, spyware, or other malicious code.

A 2022 study by HP Wolf Security found a 123% increase in destructive cyberattacks that permanently destroy data or render software unusable. The cost of recovering from such an attack averaged $1.4 million for victim organizations. Installing untrusted software like SlickVPN‘s unverified app could potentially expose individuals to this type of devastating outcome.

Insecure and Vague Technical Practices

SlickVPN‘s website copy is light on technical specifics. Unlike leading VPN providers, SlickVPN does not transparently share details about its encryption standards, VPN protocols, or security features.

Industry-standard VPNs use AES-256 bit encryption, which has never been known to be cracked. Top protocols like WireGuard and OpenVPN are open source, meaning they have been vetted by security researchers for proper implementation. Cutting-edge VPNs will often commission third-party security audits to validate their no-logging policies and address any vulnerabilities, then publish the results.

SlickVPN claims to use "industry standard" encryption and protocols like IPSec, PPTP, and OpenVPN. However, the outdated and insecure PPTP protocol is a strange inclusion, while modern options like WireGuard are noticeably absent. There is no mention of encryption key length.

SlickVPN also provides no technical details on how it implements a kill switch, IP/DNS leak prevention, split tunneling, or obfuscation technology to hide VPN traffic. These are all standard features I would expect from a quality VPN in 2024.

Without transparency and specifics, it‘s impossible to gauge the true security of SlickVPN‘s infrastructure and software. For all we know, shoddy coding practices could introduce critical vulnerabilities. I cannot simply take SlickVPN‘s vague marketing claims at face value given the lack of evidence.

Based in Privacy-Unfriendly USA

Another major concern is that SlickVPN is headquartered in the state of Florida, USA. While an American base doesn‘t automatically disqualify a VPN provider, it does introduce risks due to the nation‘s membership in the 5 Eyes, 9 Eyes and 14 Eyes international surveillance alliances.

VPNs are subject to the laws and regulations of the country where they are incorporated. Under gag orders and subpoenas, they can be secretly compelled to log user activity and hand it over to government agencies, even if their marketing claims otherwise.

The United States has a troubling history of online surveillance and anti-privacy legislation, from the Patriot Act to the PRISM program. Even if a US-based VPN isn‘t actively logging, authorities may secretly force it to start. In 2024, Surfshark reported receiving a Grand Jury Subpoena demanding customer information, showcasing the risks American VPNs face.

For maximum privacy and security, I recommend choosing a VPN headquartered in a nation with strong privacy laws and no mandatory data retention, such as Panama, Malaysia, or the British Virgin Islands. VPN leaders like NordVPN and ExpressVPN are strategically located in these countries for good reason.

Poor Support and Unresponsive to Refund Request

SlickVPN‘s customer support options are lackluster compared to top-rated VPNs. There is no 24/7 live chat, only a basic web form that doesn‘t inspire confidence. I submitted a refund request after being unable to install the app on macOS and never received a response.

When your privacy and security are on the line, you need fast, accessible support from VPN experts. Even a small issue or question should be addressed promptly to minimize any window of risk. Quality VPNs offer round-the-clock live chat and email support, extensive knowledge bases, and even remote desktop assistance.

Lack of Third-Party Validation

As mentioned earlier, SlickVPN makes no indication that it has undergone any independent security audits or penetration testing. In contrast, all of our top-recommended VPNs have published results from multiple audits by reputable security firms.

• NordVPN has passed audits of its no-logs policy and infrastructure security by PricewaterhouseCoopers and VerSprite.

• Surfshark has been audited by Cure53 for its browser extensions and Deloitte for its server infrastructure.

• ExpressVPN has undergone extensive audits from PwC, Cure53, and F-Secure.

These audits are conducted by independent firms with strong reputations in cybersecurity. They scrutinize the VPN‘s code for vulnerabilities, attempt to penetrate its architecture, and verify security claims like a no-logging policy. The results are published in full so customers can see the outcome.

This type of transparency and validation by outside experts is critical for building trust in a VPN service. The fact that SlickVPN hasn‘t undergone any independent auditing is yet another red flag that I cannot overlook as a security professional.

Unknown Track Record and Reputation

Finally, SlickVPN is a relatively unknown provider with little to no track record or reputation in the VPN industry. Leading VPNs like NordVPN and ExpressVPN are well-established companies with millions of customers, while SlickVPN barely registers.

As of 2024, NordVPN has a 15% share of the consumer VPN market with over 14 million customers. Surfshark has over 3,200 servers across 100 countries. These numbers dwarf SlickVPN‘s 150 servers in 45 countries.

Mindshare and adoption are important factors in the VPN world, as they incentivize providers to protect their reputations and be accountable to a large customer base. Tiny, unknown VPNs could easily pull an "exit scam" by shutting down and disappearing with user data.

Without a proven track record, extensive third-party validation, and a large user base keeping them honest, small VPNs like SlickVPN are risky. I heavily factor reputation into my VPN recommendations as a security consultant.

Conclusion: SlickVPN Not Recommended, Use Well-Established VPNs Instead

After extensively researching SlickVPN and attempting to test the service, I cannot recommend this provider due to the myriad red flags and unknowns. From the unverified app blocked by Apple to the outdated protocols and lack of security audits, SlickVPN simply doesn‘t meet the standards I expect from a trustworthy VPN in 2024.

When you trust a VPN to encrypt your internet traffic and safeguard your privacy, you need airtight security and transparency. SlickVPN‘s vague marketing copy, lack of technical specifics, unresponsive support, and poor reputation all raise troubling questions that I can‘t overlook.

Installing an untrusted, unverified VPN app is dangerous and could potentially infect your device with malware. I strongly advise against using SlickVPN on any platform.

Instead, I recommend sticking with reputable, proven VPN services that are transparent about their technology and have passed independent security audits. Our current top recommendations are:

1. NordVPN – Standout security features, hugely reputable brand, lightning-fast NordLynx protocol, extensive audit history
2. Surfshark – Feature-rich apps, unlimited connections, CleanWeb ad-blocker, split tunneling, Camouflage Mode obfuscation
3. ExpressVPN – Gold-standard encryption, RAM-only servers for security, Lightway protocol, proven no-logs policy

These providers lead the pack when it comes to advanced security, privacy-friendly jurisdictions, third-party validation, and user trust. With your digital life on the line, it‘s not worth gambling on an unknown VPN. Stick with an established leader that has proven its integrity and security.

As a cyber security consultant, my job is to cut through the hype and give clients clear recommendations for staying safe online. While SlickVPN makes enticing claims, it fails to back them up and sends far too many signals of an insecure, untrustworthy service. Protect yourself and your data by choosing one of the proven, well-established VPNs we recommend instead.
