EFS Data Recovery

Encrypting File System (EFS) is one of the most popular filesystem-level encryption tools available, partially due to its inclusion on most Windows operating systems. For many businesses, it offers a simple but effective way to encrypt large amounts of data quickly without the purchase of third-party software. EFS uses a symmetric encryption cipher, allowing for fast operation, and the current version of the tool meets a number of industry standards.

EFS Data Recovery

Our engineers understand common issues that affect EFS volumes and always use a case-specific process for optimal results.

When a system with EFS-encrypted data fails, you may have trouble restoring the lost information. You cannot safely use commercial data recovery software, and if your media has physical issues, you need to find a professional data recovery company that has significant experience with encrypted data.

Secure Data Recovery Services operates dozens of offices across the United States, and our experienced engineering staff provides capable, reliable services for all versions of EFS. Regardless of your encryption algorithm or depth, we can safely recover data while maintaining excellent security standards.

Secure Data Recovery Services offers:

  • Same-Day Emergency Data Recovery, Available 24/7/365
  • Free Media Diagnostics and Price Quotes
  • High Security Services
  • Custom Data Recovery for EFS-Encrypted Data
  • Fast Turnarounds and High Recovery Rates

We offer several data recovery service levels and flexible case options. Call us today to start a case or for more information.

Data Loss Scenarios for EFS Files

Encrypted files may suddenly become inaccessible due to physical media damage, RAID failures or other events. When this occurs, data recovery engineers need to perform physical repairs before transferring encrypted data to a safe, functional device. Engineers can then perform logical file repairs.

When an EFS-encrypted file becomes corrupt, data recovery engineers need to repair the file logically. We use proprietary utilities, designed specifically for the Encrypting File System, in order to provide the best possible chances of a full recovery.

Because of our experience with the EFS filesystem and with filesystem-level encryption in general, we offer high recovery rates for hard drives, RAID arrays, solid-state drives and other devices.

Safely Recovering Encrypted EFS Data

EFS uses a symmetric encryption cipher and does not pose any especially serious challenges for our data recovery engineers, provided that the username and passwords associated with the FEK are available and intact. If we have access to this information, our engineers can decrypt data in order to validate the recovery, and we can return data in an encrypted or decrypted format.

If you do not have access to the key, we can sometimes recover and decrypt the data depending on the version of EFS used to write the data and the encryption algorithm. Algorithms associated with EFS include DESX, AEX, SHA, ECC and Triple DES.

Secure Data Recovery Services' engineers take care to preserve data in its original state. Every technique that we use in our laboratories is designed to keep your media safe and secure. We create bit-by-bit copies of hard drives and solid-state drives before using any logical data recovery procedures.

If your media is physically damaged, our engineers perform repairs in a Certified Class 10 ISO 4 Cleanroom. This environment eliminates potentially harmful contaminants, allowing fewer than 10 particles per cubic foot of laboratory space. Secure Data Recovery Services is one of the only data recovery company in the United States with a certified Class 10 ISO 4 Cleanroom, and we post our certification and audit documents online for the benefit of our clients.

A Secure Option for EFS Data Recovery

Security is always our highest priority. When handling encrypted data, we take appropriate steps to preserve compliance and to give our clients a fast, reliable option for professional data recovery. As the first data recovery provider with a SSAE 18 Type II Certification, we maintain our facilities with regular audits and testing. We are a member of the Information Systems Security Association (ISSA) and are committed to maintaining the best possible security standards in our facilities.

Our security certifications include:

  • PCI Security Certification
  • SAS 70 Certification
  • SSAE 18 Type II Certification
  • General Services Administration (GSA) Certified Contractor

We offer custom data recovery solutions for EFS-encrypted media. Whether you need to meet high-security federal requirements or you need data encrypted with a non-EFS tool, Secure Data Recovery Services will help you choose appropriate options for your case.

Scheduling Media Diagnostics and Starting a Case

If you cannot access data on EFS media, contact Secure Data Recovery Services to schedule free diagnostics. Never attempt to recover missing data from your original media with software.

Our engineers can give you a quick synopsis of your recovery options, including price quotes and turnaround times, within 24 hours of receiving your media. To start a new case or for more information, contact us today to speak with a certified data recovery professional.
