How to use WinRAR’s Encryption Feature in Law Firms

Law firms require file compression and encryption software that provides the highest level of security for both them and their clients. Ensuring that sensitive information is sent and stored safely and securely remains the top priority.

Data Leaks & the Threats they Pose

Data leaks pose a genuine threat to law firms. Legal professionals are a top target for cybercriminals and other nefarious individuals who want to amass as much personal data as quickly as possible. If hackers gain access to a legal office’s IT system, they have the chance to steal confidential and sensitive information about the clients and the law firm itself.

One major concern is software vulnerabilities. Not using encryption software is one of the most efficient ways for criminals to hack their way into computer systems , using existing vulnerabilities and unpatched software. Ensuring that software is kept up-to-date is one of the most important things that those working in the legal profession can do to safeguard themselves against a potential attack.

Improving awareness in law firms is essential. To introduce company-wide protocols for all users and explaining which steps to follow in the event of a security breach is crucial. Establishing a security culture within the workplace is fundamental and guaranteeing the security of the data being held is only possible if everyone is on the same page.

One of the biggest threats that law firms face is file sharing. Relying solely on email or other tools, such as Dropbox or OneDrive, puts the data being shared at high risk of interception by third parties. Email is responsible for 92% of malware infections through Phishing scams, making it one of the primary causes of data leaks. Information being shared via unsecured channels is next on the list, followed by employee’s accidental mistakes, and deliberate sabotaging of the firm by stealing and selling the confidential information to criminals.

The average cost of a data breach in the US was $7.91 million in 2018, with 64% of customers saying they are unlikely to do business with a company that has experienced a data breach in the past.

There are strict regulations governing how documents should be shared and stored in the legal field. All legal professions are required to take reasonable steps to ensure that the sensitive and confidential information regarding their clients cannot be accessed or intercepted by a third party whilst in transit or at rest. This includes files sent to or from the Cloud.

Lawyers must carry out thorough checks of the file-sharing software they intend to use for transferring and storing data, making sure that the chosen product guarantees the security of the data being exchanged to the highest possible level.

Informing clients about the file-sharing and encryption software law firms will use to communicate with them, allows the client to approve the chosen method and earn trust. Law firms should also keep backups of sensitive data that is stored on the Cloud, so that in the event of a system crash, the data can still be easily accessed with the use of file recovery solutions.

Using Encryption in Law Firms

Data encryption takes ordinary text (plaintext) and scrambles it into what appears to be unintelligible gibberish. Using the correct encryption key unscrambles the gibberish back into an ordinary text that can be read as normal.

Ideally, all information should be encrypted, protecting law firms from becoming the victims of costly leaks. Using encryption software enables law firms to comply with many regulations , for example GDPR.

Here is a look at the various uses of encryption in law firms:


Data that is sent across the internet or within an office network is referred to as “In Transit”. Because this type of data can be easily intercepted and read, it is imperative to use encryption software. This type of encryption is commonly known as end-to-end encryption and is used by many messenger services and email providers. This data encryption solution should be mandatory for any law firm.


Saved emails, documents, and other data on devices is known as “Data at Rest” — often stored on hard-drives, laptops, and mobile devices. Lost laptops, tablets, and smartphones pose immense problems for law firms because they hold so much sensitive data. Encryption at rest and encryption programs on these devices should therefore also be mandatory.


File-level encryption takes each file on your computer, tablet, smartphone, laptop, etc. and encrypts them separately. This ensures that all confidential information is only accessible to those with the correct encryption key. It means that the files are securely stored and can be safely shared.

Clients demand a certain level of security when using the traditional ways of file sharing, such as email. Law firms must comply with strict regulations regarding their handling of confidential data and must ensure it is shared in a secure and compliant way.
