Digital threats and data privacy

Data is the backbone of modern business. Ransomware attacks someone's computer every 10 minutes. Cybercriminals make mailings under the guise of well-known trademarks and brands. The result is deplorable: financial losses, loss of customer trust and legal risks. Companies that do not pay due attention to security sooner or later face the consequences: blackmail, leakage of corporate secrets, lawsuits.

What data of your company is at constant risk? Where are they stored? What information requires frequent backups? How do you preserve data that is being processed?

Data encryption
Even if attackers gain access to encrypted data, it cannot be decrypted without a key. Encryption is the key, transforming data into an unintelligible form. As a rule, data is encrypted before transmission over the network and stored in encrypted form. The user ID becomes a constant - a new level of security management. It is important to encrypt not only data on servers, but also in transmission, using TLS and VPN protocols. Emat EOOD it company develops comprehensive solutions for data protection, including encryption algorithms and key management.

Strong passwords and multi-factor authentication
No password is impossible to crack. But if a password is created for each account and is complex and unique, it's harder to break into the system. Modern systems require complex passwords, the use of password managers and multi-factor authentication (MFA).

Multi-factor authentication (MFA) - code from SMS or biometric recognition - provides an additional layer of verification. Emat ltd tests the security systems of client companies for penetration, simulates the actions of hackers, identifies vulnerabilities and assesses the level of protection of computer networks. At this stage, they look for flaws and breaches that could later become a portal for cyber attacks.

Regular software updates
In 2025, attacks through zero-day vulnerabilities are becoming more and more common. Vulnerabilities in software are very often the cause of unauthorised access to data. To minimise the risks, operating systems, applications and anti-virus software should be updated regularly. All virtual machines, databases, storage and IoT should be connected to threat detection services.

Sensitive computing technology
Robust and proven encryption technologies have long existed to protect data that is at rest and in transit. Protecting data that is in processing, on the other hand, is very difficult. This is a new trend that utilises trusted execution environment (TEE), a confidential computing technology.

TEE is an isolated execution environment inside the processor designed to securely store data and process critical operations. This functions as a separate segment of the infrastructure that can only be accessed by individual programmes approved by the user.

User education
A Forester study found that 40% of data breaches are due to insider threats, with employees and partners being the primary sources of these threats.

The human factor is one of the weakest points in cybersecurity. Today, when the same user can work from multiple locations, accessing the network from different devices and applications, it is quite difficult to create secure login systems. Preparing users to recognise phishing attacks, malicious attachments and other fraudulent schemes can significantly reduce risks.

Employees need to know how to respond to potential threats and attacks. Understand phishing, smishing and fraud schemes. Know the rules for using complex passwords and software updates.

Access and privilege management
Limiting access to data to only when it is truly necessary and granting the minimum privileges required is a strategy that works well.

60% of companies attacked by ransomware pay a ransom to get their data back. Enterprise data thefts and malware installations are usually the fault of insufficiently attentive employees. More often than not, they are unaware of the danger they face.

Back up your data regularly
3-2-1: Three copies of data, on two different media, one in the cloud or offline is a convenient data backup strategy. Data protection is an ongoing process. You need to be proactive about the threat, using all available methods and technologies in combination to help ensure protection. By backing up your data, you can minimise losses in the event of a data breach or attack. It is important to keep copies of data in secure and separate locations.

In the event of a leak of your company's data, cloud backup can help limit the impact on business operations.

Monitoring and incident detection
SIEM (Security Information and Event Management) and SOC (Security Operations Centre) systems can detect anomalies and prevent attacks. In 2025, behavioural analysis and machine learning technologies are used to detect threats in real time.

Technologies that can automatically detect unauthorised attempts to access a network or computer. IDS monitors traffic and analyses user behaviour on the network, looking for anomalies that may indicate a hack or attack.

Network segmentation and microservices
Network segmentation is the division of infrastructure into isolated segments. Segmentation helps to limit the spread of threats and minimise potential damage. In a microservice architecture, each service operates independently, which also reduces the likelihood of a massive system breach in the event of an attack.

Artificial intelligence tools
AI tools play an important role in modern cybersecurity. They are able to analyse vast amounts of data, identify anomalies and offer solutions to prevent threats. Machine learning helps systems adapt to new types of attacks, improving proactive defence.

ChatGPT, Google Gemini, Claude, Jasper AI and other AI tools can be used to automatically detect intrusions and anomalies in the network. Using big data analytics and machine learning, ChatGPT can identify potential threats and prevent cyberattacks.

Emat development uses integration testing tools, creates automated tests. Emat EOOD programmers use the approach of continuous testing and integration at the early stages of development. This allows us to automate testing processes as much as possible.
