How Encryption Works and How It Keeps Your Data Safe

Synology

Encryption has protected private data for thousands of years, from the simple substitution ciphers used in Ancient Rome to the Babington Plot, which sealed Mary, Queen of Scots’ fate, and the Navajo code, which helped keep Allied communications safe during World War II. No matter what time period, one thing is always true: safe communication is what keeps people alive.

Encryption used to be a luxury during wartime, but now it is an essential part of digital security for all businesses. As threats get more advanced, companies depend more and more on Epis Technology’s secure Synology deployments to keep their data safe at all levels.

What does it mean to encrypt?

Encryption changes readable data into unreadable code that can only be read with the right key. The word comes from the Greek words en (“in”) and kryptos (“secret”). The basic idea is still the same, but modern encryption has become a very advanced and mathematically rigorous field.

Epis Technology helps businesses set up encryption correctly on all of their Synology systems so that sensitive data stays safe in storage, in transit, and in the cloud.

Modern Encryption: Symmetric vs. Asymmetric Symmetric Encryption

With symmetric encryption, the same key is used to encrypt and decrypt data.
It’s very fast, great for large amounts of data, and very safe when used correctly.

AES-256 is an example of a complex multi-round transformation that the U.S. government uses.

Encryption that isn’t the same on both sides

It has two keys: a public key for encryption and a private key for decryption.
Safer for environments where many people are working together, but slower and more resource-intensive.

For example, the ECC Curve25519 was made to be resistant to timing attacks and have strong security.

Feature Comparison Feature Encryption that is symmetric Keys for Asymmetric Encryption Public and private use case Encryption of large amounts of data Safe key exchange
For example AES-256 ECC Curve25519

Epis Technology makes sure that both types of encryption are used in the right way in Synology systems, taking into account workload and risk profile to find the right balance between speed, performance, and security.

Encryption in Daily Life, but Not All Encryption Is the Same

Encryption is the basis for:

Banking online
Systems for healthcare
Messaging that is safe
Services in the cloud
Websites (HTTPS)

But many apps offer “encrypted services” while keeping the keys to decrypt them, which is also called “server-side encryption.” This means that the provider might be able to get to user data.

Epis Technology makes sure that clients don’t fall into this trap by using true end-to-end encryption across all Synology environments, where keys are only accessible to the company.

Synology and Epis Technology: The Right Way to Protect Business Data

Synology uses encryption at many levels, and Epis Technology sets up, manages, and checks these layers of encryption to make sure they are completely secure:

Volume Encryption: Keeping All of Your Storage Safe

A volume is a logical storage space in a Synology system. There are two keys used for Synology volume encryption:

Data Encryption Key: encrypts all data that is stored

Volume Encryption Key: locks and unlocks access and keeps the data key safe.

Both can be kept on your own computer or in a secure external vault that follows KMIP standards.

Epis Technology sets up:

Integration with a secure key vault
Policies for auto-unlocking
Keys for recovery
Extra protections for storing keys

This makes sure that your encrypted volumes stay unbreakable and accessible, even when things go wrong.

Granular, secure access control for shared folders

AES-256 keys are used to encrypt certain folders in a shared folder. Even if a bad person takes out the drives:

You can’t read encrypted folders without their key.

Epis Technology helps businesses:

Manage hundreds of encrypted folders for different teams
Set up access with zero trust
Enforce fine-grained permission governance
Keep up with audit-ready access logs

Encryption in Backups and Cloud Storage

Hyper Backup: Full Encryption for Backups and Restorations

Hyper Backup has two layers of encryption:

AES-256 for speed
ECC Curve25519 for safe key exchange

Epis Technology makes sure that encryption is always used on:

Backups from one Synology to another
Backups from Synology to C2 cloud
Strategies for DR off-site
Environments for multi-site replication

Snapshot Replication: Your Encrypted Time Machine

Snapshot Replication makes copies of your data that are almost instant. Along with encryption:

Versions are safe
Ransomware can’t change historical snapshots
Getting better happens almost right away.

Epis Technology sets up:

Scheduled snapshots
Keeping snapshots that can’t be changed
Replication in multiple locations for disaster recovery

C2 Storage: Public Cloud with Encryption, No Access for Synology

AES-256 and TLS encryption are used by C2 Storage.
Synology can’t even get to client data because the encryption keys never leave the customer’s space.

Epis Technology makes sure that hybrid cloud protection works without any problems by:

Important separation
Safe move to C2
Retention policies based on compliance
Checking and keeping an eye on integrations

Encryption: Full Cyber Resilience with Epis Technology

Encryption by itself isn’t enough. New threats need:

Backups that can’t be changed
Replication across multiple sites
Safe key handling
Access controls with no trust
Constant checking
Redundancy in the cloud

This is where Epis Technology becomes very useful.

Epis Technology provides a complete, enterprise-ready Synology security architecture that includes:

Setting up encryption and audits
Designing a backup and disaster recovery plan
Combining public and private clouds
Enforcement of immutable backups
Retention based on compliance
Managed monitoring and help 24/7

Encryption is powerful, but it works even better when done by an expert.

Synology has a strong encryption system.
Epis Technology makes sure that it is set up, run, and protected the right way.

With Epis Technology:

Your keys for encryption stay yours.
Your backups are safe from harm.
Your files are safe for the whole time they are stored.
Your infrastructure is safe and compliant at the enterprise level.

Epis Technology makes sure that your data stays private, safe, and completely under your control, from the edge to the data center to the cloud.
