What is Encryption and Why is it Important?

Ever felt that uneasy knot in your stomach when thinking about the security of your organization's sensitive data?

You're not alone. In today's digital landscape, the threat of data breaches isn't just a distant possibility. And let's be honest, the stakes are high. Whether you're a legal professional ensuring compliance, a law enforcement officer handling confidential information, or an IT security expert tasked with safeguarding systems, the question remains: how can you effectively protect your most valuable data? The answer may be encryption.

Your robust IT infrastructure, skilled team, and secure networks may seem to protect your organization, but if your data remains unencrypted, you are vulnerable to a data breach. A single successful attack, such as a stolen laptop or unsecured server, could expose your company's sensitive information to unauthorized access.

This is not just a possibility. You organization could be facing leaked confidential employee details, customer credit card numbers, or proprietary company secrets—all of which can lead to costly fines and a damaged reputation.

The aftermath? Downtime, financial losses, and frantic damage control. Unfortunately, many organizations still rely on outdated or insufficient security measures. This unknowingly leaves the door wide open for cybercriminals. But luckily, organizations like yours don't have to let a breach occur under your watch. Encryption is the missing link in your IT strategy, and ignoring it could be the costliest mistake you make.

But what is encryption and why is it important for your organization? In this blog post, we'll be exploring just that.

The Insecurity of Data in the Digital Age

Organizations today, regardless of industry, collect and store massive amounts of data, much of it sensitive. Legal teams deal with confidential client communications. An organization's IT and security staff face the daunting task of defending against increasingly sophisticated cyber threats, and compliance officers must ensure the organization is meeting strict data privacy laws. The stakes couldn’t be higher.

But here’s the painful truth: Data is vulnerable.

In the first half of 2024 alone, there were 1,571 data breaches reported, a 14% increase from the same period in 2023. This year is already on track to surpass the record-breaking 3,203 data events reported in 2023. Phishing, malware, or even simple human error can expose your organization's data in an instant, leading to millions of dollars in fines and severely damaging your reputation. If your organization handles any form of sensitive information, you’re playing a high-stakes game of digital defense—and the rules are constantly changing.

Let’s take a look at the root cause of this vulnerability: unencrypted data.

What Happens When Data Isn't Encrypted?

When data isn’t encrypted, it’s as exposed as a postcard in the mail. Anyone with access to it—whether during transmission or storage—can read it in plain text. Think of all the sensitive information your organization handles: financial records, legal documents, healthcare information, and customer details. If you’re not encrypting that data, you’re practically inviting bad actors to exploit it.

Here’s where the real pain sets in:

• Legal Repercussions: Non-compliance with regulations like GDPR, HIPAA, or CCPA can result in massive fines, sometimes reaching tens of millions of dollars.
• Reputational Damage: Sensitive client information can often get leaked in a data breach. Your customers trust you with their data; a breach can shatter that trust.
• Financial Loss: A breach can disrupt business operations, cost you clients, and result in lawsuits—all of which add up to huge financial losses.
• Data Manipulation or Theft: Without encryption, attackers can alter or steal your data, leading to operational chaos or loss of intellectual property.

Without encryption, you’re left with a glaring vulnerability that bad actors are eager to exploit.

What is Encryption?

Now that we’ve looked at the consequences, let’s talk about the solution: encryption.

At its core, encryption is the process of converting plaintext data (readable information) into ciphertext (unreadable, encoded information) using an algorithm. The only way to revert this encrypted data to its original form is through a decryption key. Only authorized parties have access to this key.

But encryption isn’t just about making data unreadable to outsiders. It’s about ensuring that even if unauthorized individuals manage to intercept or access your data, it remains completely useless to them.

The Two Types of Encryption

1. Symmetric Encryption: This type of encryption uses the same key for both encryption and decryption. It's fast but requires secure key distribution. An example is the Advanced Encryption Standard (AES).
2. Asymmetric Encryption: There two keys in asymmetric encryption, one public and one private. The public key encrypts the data, and the private key decrypts it. This is more secure but slower. A common example is RSA encryption.

Why Is Encryption Important?

Encryption has evolved from being a niche technology to becoming the backbone of modern data security. But why is it so critical for organizations today? Let’s break it down.

1. Data Protection in Transit and at Rest: Whether your data is traveling across networks or sitting in storage, encryption ensures it’s safe. In transit, encrypted data is protected from being intercepted, while at rest, it remains secure from unauthorized access.
2. Compliance with Regulations: Legal mandates like GDPR, HIPAA, and CCPA require encryption for sensitive information. If your organization is handling health records, financial data, or customer information, encryption helps you stay compliant and avoid hefty fines.
3. Mitigating Breach Fallout: Even if a breach occurs, encrypted data is useless to cybercriminals without the decryption key. This drastically reduces the potential damage of a security incident.
4. Ensuring Data Integrity: Encryption ensures that data hasn’t been tampered with. In industries like finance and legal, where document integrity is paramount, encryption offers a method to confirm that data remains unchanged.
5. Building Customer Trust: Customers and clients are becoming more aware of how their data is handled. Implementing robust encryption protocols demonstrates that your organization takes data privacy seriously, fostering trust and long-term loyalty.
6. Preventing Insider Threats: Encryption isn’t just about protecting data from external threats. Insider threats—whether malicious or accidental—pose a significant risk. With encryption, even employees with access to certain data sets can’t decrypt information they’re not authorized to view.

Best Practices for Implementing Encryption in Your Organization

Encryption is highly relevant to organizations that house data. But the question is, how do you do it best? Here are some of the best practices for encryption that you can follow:

Classify Your Data

Not all data requires the same level of protection. Start by classifying your data based on sensitivity and implement encryption protocols that match each level.

Use Strong Encryption Algorithms

Weak encryption is as bad as no encryption at all. Stick to industry-standard encryption algorithms, such as AES-256 or RSA-2048, to ensure your data is adequately protected.

Manage Encryption Keys Securely

Your encryption is only as strong as your key management system. Use secure methods for storing and distributing keys, and ensure that only authorized individuals have access to them.

Encrypt at Multiple Layers

Don’t rely on just one layer of encryption. Encrypt your data at the file, disk, and application level for comprehensive security.

Regularly Update Encryption Protocols

As encryption technologies evolve, so do the threats that seek to break them. Ensure your organization is using the latest encryption standards and protocols to stay ahead of potential vulnerabilities.

Secure Your Data Today

Encryption is not just a checkbox on a compliance list. It’s a fundamental practice for protecting your organization’s most valuable asset—its data. Whether you’re a legal officer safeguarding sensitive client information or a CISO defending against cyberattacks, encryption is an indispensable tool for maintaining security, trust, and compliance.

But encryption is just one part of a broader cybersecurity strategy. Implementing it effectively requires not only the right tools but also the expertise to ensure your organization’s data remains safe in an ever-evolving digital landscape.

It’s time to take a proactive approach to data security. The cost of inaction? Far too high to ignore.
