Data loss prevention is the process of identifying, monitoring and protecting sensitive data from threats.
Data loss prevention (DLP) tools are a subset of cybersecurity technologies that help to protect one of your organisation's most sensitive assets: information.
While there are many different types of data security technologies, DLP is unique in that it focuses on protecting information based on its sensitivity.
This can include anything from customer contact details held in an on-premise server to ID verification documents sent by email.
The average cost of a data breach is USD $4.45 million (GBP £3.53m) according to IBM's Cost of a Data Breach Report.
How would you feel if your company lost all its customer records?
Or if it was subjected to fines because an employee accidentally sent a file containing client information over email? Data breaches can be a source of anxiety and stress, impacting employee wellbeing.
If someone steals customer details or your company's intellectual property, they likely intend to use it for their benefit.
That could mean serious legal trouble as well as losses in revenue if customers are negatively affected and take their business elsewhere.
Data security policies govern the use of company devices and networks to ensure robust data security and prevent data breaches.
It can include remote wipe protocols, regular backups, and sign-in and out policies for particularly data sensitive devices.
Encryption is vital for ensuring your sensitive data can't be accessed by anyone who picks up one of your devices or intercepts communications.
It disguises data with secret "keys" so that only authorised individuals, apps, and networks can gain access.
Not all cybersecurity products are created alike — consumer cybersecurity software might not cut it when you're responsible for hundreds, if not thousands of data points.
Using enterprise cybersecurity software will keep your security in line with the latest regulatory guidance for dealing with customer information.
Regularly updating and backing up software and devices is essential to maintain good data security hygiene.
Updating operating systems and apps with the latest patches will help you get protection against the latest attacks used by cyber threat actors.
In some business communications, it might be necessary to establish that you are dealing with the right people, especially when transferring sensitive documents.
Using communications software and processes that give you the power to identify, or 'authenticate', customers can prevent you from communicating the wrong information to the wrong people.
Email data loss prevention (DLP) is a catch-all term for security solutions that help to protect business and personal information by preventing the accidental or intentional release of confidential data.
Email DLP can be used to protect both business and personal email accounts, on all types of devices.
It works by recognising sensitive information (such as phone numbers, credit card numbers, bank details) wherever it appears in an email message.
Different email DLP solutions may block an email from sending or surface additional checks for the sender to verify they are sure they want to send their email.
Mailock, our secure email service, gives you the option to automatically encrypt emails containing particular information or take the sender through such additional checks.
Here are some steps you can take to prevent email data loss:
If there's a possibility that people may use email to transfer sensitive information or documents, you need to make sure you have a secure email solution in place to protect that data.
A secure email solution like Mailock can be deployed easily and integrated into your email workflow.
Make sure that your email is encrypted and protected with authentication. If you're sending something highly sensitive, you'll want to make sure it can only be accessed by the person you intend to receive it.
Secure email solutions like Mailock give you the ability to verify recipient ID in various way, such as a code sent to a device or a question and answer.
If you aren't using secure email, it's better to communicate with colleagues and clients over video call instead of email when dealing with sensitive information, looking out for signs of deep faking.
There are ways to easily prevent data loss in email.
You should choose a prevention method based on the needs of your organisation and the resources available to implement it effectively.
If not, you should not use email for sensitive information.
