Data encryption is now at the heart of corporate cybersecurity. By converting sensitive information into an unreadable format without an access key, it prevents any unauthorized use, even in the event of a breach.
Put simply, encrypting your data is like locking it inside an unbreakable vault that only the right keyholder can open.
Key Takeaways
Data encryption turns sensitive information into unreadable content without an access key.
It is essential for protecting remote access and preventing corporate data leaks.
There are several encryption methods, including symmetric and asymmetric, which should be chosen based on use cases.
An effective strategy combines encryption technologies with isolation and access management.
Encryption is the process of converting readable data into an encrypted format, unreadable without the proper decryption key. This mechanism protects data confidentiality, whether the data is in transit or stored (data at rest).
It is an essential response to today’s threats.
Encryption relies on encryption algorithms that apply complex mathematical calculations to transform data. There are two main models:
Symmetric encryption: a single secret key is used to encrypt and decrypt the data.
Asymmetric encryption: it uses two keys, a public key to encrypt and a private key to decrypt.
These systems are designed to withstand brute force attacks and other intrusion attempts.
Encryption safeguards sensitive information such as personal data, confidential documents, and intellectual property.
A leak of unencrypted data can expose a company to GDPR penalties, reputational damage, and significant legal costs.
In a world where hybrid work and remote connections are the norm, encryption ensures that transmitted data remains inaccessible to unauthorized parties.
Reemo solutions go further by combining encryption with environment isolation, containerization, and Zero Trust principles to secure every remote connection.
In the event of a breach, encryption renders stolen data unusable to the attacker, significantly reducing both operational and financial consequences.
Data Encryption Standard (DES), now obsolete for critical uses, made history as the encryption standard adopted by the US government.
An improvement on DES, applying the process three times for stronger security. Still used in some financial systems but replaced in modern environments.
AES (Advanced Encryption Standard) is today’s most widely used encryption standard, particularly AES-256. It combines robustness with performance.
An asymmetric system based on factoring large numbers, widely used for digital signatures and securing communications.
A fast and flexible symmetric algorithm known for its security and used in various applications.
A historically popular stream cipher, now discouraged for new projects due to known vulnerabilities.
Adopt proven standards:
SSL/TLS for communications
AES-256 for storage
Secure remote access solutions like Reemo
End-to-end encryption (E2E) for exchanges
At Reemo, encryption is combined with isolated and controlled environments. This protects not just the data, but also remote workstations and critical resources.
Even the strongest encryption is useless if users compromise keys or bypass procedures. Train your teams and integrate encryption into daily workflows.
Some ransomware encrypts victims’ data to render it inaccessible.
Poor Key Management Can Endanger the Whole System
Losing a key, storing it unprotected, or sharing it recklessly puts all data at risk.
Quantum computers could eventually break some existing algorithms. Setting up monitoring and preparing for post-quantum algorithms is essential.
Reemo offers a secure platform with advanced encryption, environment isolation, and centralized access management. Whether for hybrid teams, contractors, or virtualized environments, we help you protect information while maintaining performance.
Use tools and protocols suited to your needs: AES for storage, SSL/TLS for communications, and secure remote access solutions that avoid VPNs, which are too often in the news for vulnerabilities.
It is the process of converting readable information into a coded format, unreadable without the correct key, to ensure confidentiality and integrity.
