For each category, I‘ll dive into the technical details, compare popular options, and discuss privacy considerations for developers. I‘ll also explore the latest privacy trends and share some best practices for mitigating data leaks. Let‘s get started!

VPNs: Securing Your Web Traffic

A VPN is an essential privacy tool that encrypts your internet traffic and masks your true IP address by routing your traffic through a secure tunnel to a server operated by the VPN provider. This protects your online activity from snooping by your ISP, hackers, or other entities.

When evaluating VPNs, I prioritize the following features:

• Strong encryption (256-bit AES or ChaCha20)
• Well-vetted VPN protocols (OpenVPN, WireGuard, IKEv2)
• Strict no-logging policy (independently audited)
• Large server network with good geographic distribution
• Fast connection speeds (at least 50 Mbps)
• User-friendly apps for major platforms (Windows, macOS, Linux, iOS, Android)
• Responsive customer support and knowledgebase

My top VPN picks for 2019 are:

1. ExpressVPN – With 3,000+ high-speed servers in 94 countries, ExpressVPN is known for its consistently fast speeds, averaging over 80 Mbps in my tests. It uses 256-bit AES encryption and supports OpenVPN, L2TP/IPSec, and IKEv2 protocols. The easy-to-use apps offer useful features like split tunneling and a kill switch. ExpressVPN boasts a verified no-logging policy, 24/7 live chat support, and a 30-day money-back guarantee. Pricing starts at $8.32/month.

2. NordVPN – NordVPN operates an extensive network of 5,200+ servers across 62 countries. Its newly updated apps feature a sleek UI and support OpenVPN and NordLynx (WireGuard) protocols with 256-bit AES encryption. Handy features include double VPN, Onion over VPN, and P2P servers. NordVPN follows a strict no-logging policy and has undergone multiple security audits. Plans start at $3.49/month.

3. ProtonVPN – From the team behind the popular ProtonMail service, ProtonVPN offers a solid VPN solution with a strong focus on privacy and security. Its Secure Core architecture routes traffic through privacy-friendly countries like Switzerland and Iceland before exiting through a second VPN server for enhanced protection. ProtonVPN uses OpenVPN and IKEv2 with 256-bit AES encryption and 4096-bit RSA key exchange. It keeps no logs and has gone through security audits. Plans start at $4/month.

When integrating a VPN into your development workflow or recommending one to users, consider the following:

• Avoid free VPNs as they often log user activity or inject ads to monetize the service. If a VPN is free, you‘re likely the product. Stick with reputable paid providers.
• For maximum security, use the OpenVPN protocol with 256-bit AES encryption. WireGuard is a newer protocol that offers faster speeds and easier configuration.
• Test for WebRTC and DNS leaks to ensure your VPN is properly hiding your IP address. Use tools like https://ipleak.net/ and https://dnsleaktest.com/.
• Implement a kill switch to block all internet traffic if the VPN connection drops unexpectedly. Most VPN apps have this feature built-in.

Encrypted Messaging: Protecting Your Communications

To keep your digital communications truly private, it‘s crucial to use an end-to-end encrypted messaging app. With end-to-end encryption, only the sender and intended recipient can read the messages. Even if the messaging provider‘s servers were compromised, the encrypted messages would be indecipherable without the private keys.

Key factors to consider when choosing an encrypted messaging app include:

• End-to-end encryption protocol (Signal Protocol, OTR, etc.)
• Open-source code for transparency and auditing
• Self-destructing messages and media
• Cross-platform support (iOS, Android, Desktop)
• Voice/video calling and file sharing capabilities

My recommended encrypted messaging apps are:

1. Signal – Widely regarded as the gold standard for secure messaging, Signal is a free and open-source app that uses the Signal Protocol for end-to-end encryption. It offers secure messaging, voice/video calls, and file sharing. Signal stores minimal metadata and encrypts messages at rest. The app is regularly audited and endorsed by privacy experts like Edward Snowden. Available on iOS, Android, and Desktop.

2. Wire – Wire is a sleek, cross-platform messaging app that uses the Signal Protocol for end-to-end encryption. It offers secure messaging, voice/video calls, and file sharing, along with useful features like timed messages and secure group chats. Wire is open-source, regularly audited, and stores minimal metadata. The app is free for personal use, with paid plans for businesses.

3. Wickr Me – Wickr Me is a popular secure messaging app that offers self-destructing messages, screenshots, and files. It uses the Signal Protocol for end-to-end encryption and doesn‘t store metadata or user information. Wickr Me features secure voice calling, file sharing, and anonymous accounts. The app is free and available on iOS, Android, and Desktop.

For developers building messaging apps, consider the following privacy best practices:

• Use a well-tested, open-source encryption protocol like the Signal Protocol or OTR.
• Generate encryption keys on the client-side and never store them on your servers.
• Minimize logging and metadata collection. Don‘t store message contents or user IP addresses.
• Implement self-destructing messages and secure file sharing.
• Allow users to create accounts without requiring personal information like phone numbers or email addresses.
• Regularly audit your app‘s security and be transparent about your practices.

Password Managers: Taming Your Passwords

Using strong, unique passwords for every online account is one of the most effective ways to prevent unauthorized access and data breaches. However, creating and remembering dozens of complex passwords is a daunting task for most people. That‘s where password managers come in.

A password manager generates, stores, and encrypts all your passwords in a secure vault, which you can access with a single master password. This allows you to use strong, unique passwords for every account without having to remember them individually.

When choosing a password manager, look for the following features:

• Strong encryption (256-bit AES or better)
• Two-factor authentication (2FA)
• Secure password generation and sharing
• Automatic password capture and autofill
• Cross-platform sync (across devices and browsers)
• Security audits and a bug bounty program

My top picks for password managers are:

1. 1Password – 1Password is a popular password manager with a clean, user-friendly interface. It uses 256-bit AES encryption to secure your vault and offers 2FA, secure password sharing, and a built-in TOTP authenticator. 1Password has been independently audited and offers a bug bounty program.

Conclusion

In this guide, we‘ve explored some of the best privacy tools across various categories, including VPNs, encrypted messaging apps, password managers, and private email services. We‘ve also discussed some privacy best practices for developers and shared some eye-opening privacy statistics.

As a full-stack developer, I believe that privacy should be a fundamental human right in the digital age. We should all have control over our personal data and be able to communicate and browse the web without fear of surveillance or exploitation. By using privacy-focused tools and services, and by building software with privacy in mind, we can work towards a more secure and privacy-respecting internet.

However, it‘s important to remember that no single tool or tactic can guarantee perfect privacy. We must use a combination of tools and strategies, and remain vigilant about new threats and best practices. We should also support organizations and initiatives that fight for digital privacy rights, such as the Electronic Frontier Foundation and the Privacy Rights Clearinghouse.

Ultimately, online privacy starts with awareness and education. By staying informed about privacy issues and tools, and by spreading awareness to others, we can all make a difference in the fight for digital privacy. As developers, we have a unique opportunity to lead by example and build software that respects user privacy by default. Let‘s work together to create a more private and secure internet for all.
