Data breaches aren’t just making headlines—they’re destroying reputations and draining bank accounts. Whether you’re securing confidential work files, personal photos, or sensitive client information, leaving your data unencrypted is like leaving your front door wide open.
Encryption isn’t “nice to have” anymore—it’s non-negotiable. The question isn’t if you should encrypt your files, folders, and drives, but how. And that’s where choosing the best encryption software comes in.
Folder Lock has built a reputation among dozens of contenders for delivering rock-solid security without sacrificing usability. But before we break down its features, let’s look at the broader encryption software landscape in 2025.
Choosing encryption software isn’t just about ticking boxes—it’s about matching technology to your real-world needs. The best tools balance security, speed, and simplicity.
Here’s what matters most:
Strong encryption algorithms – AES-256 is the gold standard for file and folder encryption standard, offering military-grade protection.
Platform compatibility – Works on Windows 10, Windows 11, macOS, and ideally mobile devices.
Flexible encryption modes – File-level, folder-level, and full-disk encryption.
Ease of use – Security shouldn’t require a cryptography degree.
Extra features – Password protection, secure backups, cloud integration, encrypted storage, and file shredding.
Think your vacation pics or old invoices aren’t valuable? Think again. Hackers love low-hanging fruit. Stolen personal data fuels identity theft, targeted phishing, ransomware, and blackmail. Encrypting sensitive data isn't paranoia; it's basic digital hygiene.
The Cloud Isn't Safe: Google Drive, Dropbox? They're great for syncing but terrible for privacy by default. Your files are only as secure as your password (and we all know how those go). Encrypt Google Drive files before uploading; they're vulnerable to breaches or snooping admins.
USB Drives = Data Landmines: If you lose an unencrypted thumb drive, you don't just lose $10; you potentially lose everything on it. Encrypt USB drives and external hard drives, making them useless bricks to anyone but you.
Email is a Postcard: Sending your bank statement or contract via regular email? It’s like writing it on a postcard. Encrypt files for email – especially PDFs (encrypt PDF for email) or ZIPs (encrypt zip file with password) – to ensure only the intended recipient sees it.
Here’s a quick look at some top categories:
Best encryption software for Windows 10 & 11: Folder Lock, VeraCrypt
Best encryption software for Mac: Folder Lock, FileVault, Encrypto, Espionage
Best free encryption software: VeraCrypt, BitLocker (Windows Pro), Cryptomator
Best folder encryption software: Folder Lock, Kruptos 2
Best encryption for data at rest: AES-256-bit implementations with zero-knowledge architecture
Folder Lock: Why It’s More Than Just “Another” Encryption Tool
Folder Lock has been around for years, but in 2025, it’s not just surviving—it’s evolving. It’s not a one-trick pony. It’s an all-in-one suite that combines file and folder encryption, USB encryption, secure backups, and file shredding into a single, polished package.
Folder Lock’s core feature is AES-256-bit encryption, which is the same standard used by governments and financial institutions. You can encrypt a folder on Windows 10 or Windows 11 in seconds.
Encrypted files are stored in secure lockers—password-protected virtual drives that keep your data inaccessible without the correct credentials.
Portable storage is a hacker’s dream if lost or stolen. With Folder Lock, you can encrypt USB and external hard drives so that your data stays unreadable even if they fall into the wrong hands.
This makes it a strong contender for the best USB and external drive encryption software in 2025.
Sometimes you don’t need full encryption—you just need a quick lock. Folder Lock lets you password-protect folders, files, and even applications. That means no more prying eyes on shared computers.
Need your data on the go but still secure? Folder Lock supports encrypted file storage that can sync with services like Google Drive and Dropbox. You can even encrypt Google Drive files before upload for proper client-side security.
Sending sensitive files over email? Folder Lock can encrypt files for email or create password-protected ZIPs. Whether it’s contracts, personal IDs, or financial records, you can control who can open them.
Encryption keeps data safe while stored—but what about when you delete it? Folder Lock includes a file shredder that permanently overwrites files, making recovery impossible.
This is a must-have for compliance with GDPR, HIPAA, and other privacy regulations.

The Advanced Encryption Standard (AES) comes in 128-bit and 256-bit flavors. Folder Lock uses AES-256 encryption for maximum protection.
It is often used for secure communications and digital signatures. However, it is less common for full data storage due to its slower performance compared to AES.
Symmetric encryption – One key for encryption and decryption (fast, ideal for file storage).
Asymmetric encryption – Public/private key pairs (best for secure transmission).
Small businesses securing client databases on Windows 10
Journalists protecting source documents on encrypted USB drives.
Healthcare providers meeting HIPAA requirements with AES-256 at rest.
Freelancers storing tax documents in encrypted cloud lockers
At rest: Data stored in lockers, USB drives, or external hard drives remains encrypted even if the device is offline.
In transit: Encrypted files sent via email or uploaded to the cloud maintain their encryption until unlocked by the recipient.
Regarding best encryption software rankings, Folder Lock consistently leads because it blends military-grade encryption, cross-platform usability, and feature depth in a package that’s both consumer-friendly and business-ready.
Decide your priority – Is it file encryption, full-disk encryption, or both?
Check platform compatibility – Windows, Mac, or mobile?
Look for AES-256 – Anything less is outdated for sensitive data.
Consider extras – Backup, shredding, and password management can save you from installing multiple tools.
Test the interface – You won’t use it consistently if it's clunky.
Is Folder Lock the best encryption software for Windows 10?
Yes. It’s one of the top choices for Windows 10 and 11 due to its AES-256 encryption, easy interface, and added features like shredding and secure cloud sync.
Can I use Folder Lock on Mac?
Yes! Folder Lock is focused on cross platform integration. It works on Mac as well. Encrypted files can still be accessed on other platforms if the correct password and decryption tools are available.
What’s the best free encryption software?
VeraCrypt is the best free, open-source option. It’s great for advanced users, but Folder Lock offers more convenience and extra tools in a paid package.
Is AES-256 really unbreakable?
For practical purposes, yes. AES-256 is considered military-grade encryption and would take billions of years to brute-force with current technology.
Does encryption slow down my computer?
Minimal impact for most modern systems. Folder Lock’s encryption is optimized for speed, so day-to-day performance remains unaffected.
What's the difference between "disk encryption software," "drive encryption software," and "full disk encryption"?
They're often used interchangeably. Disk encryption software or drive encryption software generally refers to tools encrypting entire storage devices (hard drives, SSDs, USBs). Full disk encryption (FDE) is a specific type that encrypts the entire drive, including the operating system (like BitLocker, FileVault, or Folder Lock's ability to encrypt system drives). Folder Lock also offers volume encryption (specific partitions) and USB drive encryption software/external hard drive encryption software for portable media.
Can Folder Lock encrypt databases or is it just for files?
Folder Lock is primarily designed as file and folder encryption software and drive encryption software. For live, actively used database encryption (like SQL Server, MySQL), you typically need database management system (DBMS) specific encryption features or dedicated enterprise database encryption tools. However, Folder Lock can encrypt the database files themselves when they are at rest (not actively being accessed by the DBMS), providing an extra layer of security for backups or archived databases. For ongoing protection of a live database, rely on the DBMS's built-in database encryption capabilities.
Does "cloud encryption" mean encrypting files before uploading (like with Folder Lock) or does the cloud provider do it?
Both exist, but they protect against different threats. Cloud encryption provided by the service (like Google Drive or Dropbox) often protects data from outsiders if the provider's infrastructure is breached. However, the provider usually holds the keys, meaning their admins or legal compliance actions could potentially access your data. Encrypting files before uploading (Client-Side Encryption, like Folder Lock's encrypt Google Drive files feature) means you hold the only keys. The cloud provider only stores encrypted gibberish, protecting you from provider breaches, admin snooping, or unauthorized government access. This is the gold standard for true cloud encryption privacy.
I use a VPN for encryption. Do I still need file encryption software?
Absolutely! VPN encryption (like VPN encryption) secures your data while it's moving over the internet between your device and the VPN server. It protects you from eavesdroppers on your local network (like public Wi-Fi). Data encryption software (like Folder Lock) protects your files where they are stored (on your laptop, USB drive, external hard drive, cloud storage) and when you share them (via email). If someone steals your unencrypted laptop or USB drive, a VPN offers zero protection. If you email an unencrypted file, the VPN only protects it until it leaves the VPN server. You need VPN encryption for the pipe and data encryption software for the data itself.
Can I use Folder Lock for mobile phone encryption of specific files?
Yes! While your phone's OS provides mobile phone encryption for the whole device, Folder Lock offers apps (like Folder Lock for Android and iOs) that provide app encryption – a secure vault within your phone. This lets you encrypt photos, videos, documents, and other sensitive files with an extra layer of password protection and AES 256-bit encryption, separate from your phone's general unlock. It's perfect for adding specific document encryption software-level security to your most sensitive mobile files.
What exactly is "encryption software," and why is it important?
Encryption software scrambles data using complex algorithms, making it unreadable without a unique key. Its importance lies in protecting sensitive information (personal, financial, intellectual property) from unauthorized access, theft, or exposure during breaches, ensuring confidentiality and integrity – a core goal of security awareness.
What are the key benefits of using data encryption software?
The primary benefits of data encryption include:
Confidentiality: Protects data from unauthorized eyes.
Compliance: Meets regulations (GDPR, HIPAA, PCI-DSS).
Data Integrity: Helps detect unauthorized alterations.
Risk Mitigation: Reduces impact of data breaches/loss.
Trust: Builds customer and partner confidence.
Secure Data Sharing: Enables safe transmission/storage.
What's the difference between data encryption at rest and encryption in transit? Why do I need both?
Data Encryption at Rest: Protects stored data (hard drives, databases, cloud storage, USB drives). Essential if physical/media theft occurs.
Encryption in Transit: Protects data moving across networks (email, web traffic, file transfers). Guards against interception.
Best practices demand both for comprehensive protection. Encrypting only one leaves data vulnerable elsewhere ("defense in depth").
What is End-to-End Encryption (E2EE), and is it better?
E2EE ensures data is encrypted on the sender's device and only decrypted on the recipient's device. Not even the service provider (like a messaging platform or cloud storage vendor) can access the plaintext data in the middle. It's considered the gold standard for confidentiality, especially for communications and sensitive file sharing, as it minimizes points of vulnerability.
What do terms like "Bank-Level Encryption" or "Military-Grade Encryption" actually mean?
These are primarily marketing terms, not strict technical standards.
Bank-Level Encryption: Usually implies strong, industry-standard encryption (like AES-256) used in financial contexts. Focuses on protecting transactions and data.
Military-Grade Encryption: Often refers to very strong encryption algorithms (like AES-256) and rigorous implementation standards historically associated with government/military use. The key takeaway is to look for the specific algorithm (e.g., AES-256) and validation (e.g., FIPS 140-2) rather than relying solely on these labels.
Is encryption unbreakable? How does awareness of breaking encryption factor in?
No encryption is truly unbreakable given infinite time and resources. Modern standards (AES-256) are considered computationally infeasible to break with current technology within a meaningful timeframe. Awareness of breaking encryption is crucial for security awareness:
Highlights the need for strong algorithms & key lengths (avoid weak/outdated ones).
Emphasizes the criticality of protecting encryption keys (often the weakest link).
Reinforces that encryption is one layer of security, not a magic shield; vulnerabilities like poor implementation, side-channel attacks, or social engineering can bypass it.
What are the main disadvantages or challenges of using encryption?
Key disadvantages of encryption include:
Performance Overhead: Can slow down data processing/transfer (less noticeable with modern hardware).
Complexity: Requires proper setup, management, and user understanding (security awareness training is vital).
Key Management: Securely generating, storing, distributing, rotating, and revoking keys is complex and critical. Lost keys = lost data forever.
Cost: Potential costs for software, hardware acceleration, and management tools/expertise.
False Sense of Security: Can lead to neglecting other vital security measures.
What are essential encryption best practices I should follow?
Key encryption best practices include:
Use Strong Algorithms: AES-256 is the current standard for symmetric encryption.
Robust Key Management: Use secure, dedicated key management solutions/hardware (HSMs). Enforce strong key policies (rotation, revocation).
Encrypt Everywhere: Implement both data at rest encryption and encryption in transit. Prioritize E2EE for sensitive communications.
Verify Certificates: Ensure validity of certificates used in transit encryption (TLS/SSL).
Access Controls: Encryption is useless if unauthorized users/apps have access to the decrypted data or keys. Pair with strict access controls.
Regular Updates: Keep encryption software and libraries patched.
User Training: Security awareness on the importance of encryption, password hygiene, and phishing (to prevent key theft).
How do I choose the "best" encryption software for my needs?
Consider:
Your Data: What needs encrypting? (Files, emails, drives, cloud storage, comms?)
Deployment: Device-level (full disk), file/folder, application-level, communication-specific?
Algorithms & Standards: Support for AES-256, XChaCha20, etc., and validations (FIPS 140-2).
Key Management: How are keys handled? Is it secure and manageable for your scale?
E2EE Support: Essential for private messaging/file sharing?
Usability: Balance security with user adoption.
Platform Support: (Windows, macOS, Linux, iOS, Android).
Reputation & Reviews: Independent security audits and user feedback.
If I use encryption software, do I still need other security measures?
Absolutely! Encryption is vital, but only one piece of the puzzle. You still critically need:
Strong Passwords/MFA: Protects access to devices and accounts where decryption happens.
Firewalls & Antivirus: Blocks malware that could steal data before encryption or after decryption.
Regular Backups: Protects against ransomware, corruption, and accidental deletion (backups should also be encrypted!).
Patching: Fixes vulnerabilities in OS, software, and even the encryption software itself.
Security Awareness Training: The human layer is paramount to prevent phishing and social engineering attacks that bypass technical controls.
Access Controls: Limit who can access systems and data.
The Bottom Line: Stop Scrolling, Start Locking
