SUNNET Network Security ServicesThe importance of network security in organizations

Network security services are vital to protecting corporate networks that are more vulnerable to cyber threats than ever before. With the expansion of the Internet, the use of cloud systems and connected devices, traditional security structures no longer meet current needs.

Network security is not only a technical issue, but also a key factor in preserving information and continuing the organization’s activities. Advanced attacks such as ransomware, malware and targeted intrusions have created a serious threat to organizational infrastructure.

In the event of weakness in network security, damages such as the following can occur:

🔸Loss of sensitive customer or organizational data

🔸Disruption in service or complete cessation of operations

🔸Breach of privacy and legal crimes

🔸Loss of public trust and damage to brand reputation

🔸Imposing exorbitant costs for data recovery or ransom payment

SUNNET meets this vital need for organizations across the country and region by providing specialized network security solutions.

These services are designed to protect critical information, maintain network stability and effectively deal with cyber threats.

SUNNET’s network security services include a wide range of specialized solutions, each designed to meet a specific security need. These services include:

Description	Service
First line of defense for controlling inbound and outbound traffic	Firewalls
Identify and prevent possible network intrusions	Intrusion Prevention Systems (IPS)
Identify suspicious activities and alert the security team	Intrusion Detection Systems (IDS)
Establish secure connections between users and corporate networks	Virtual Private Networks (VPNs)
Identify and remove various malware and viruses	Antivirus and anti-malware
Continuous network monitoring and analysis to identify threats	Security monitoring and surveillance

✔ Hardware and Software Firewalls

As the first line of defense against cyber threats, firewalls control incoming and outgoing network traffic based on defined security rules. By providing and configuring hardware and software firewalls from reputable brands, SUNNET helps organizations block unwanted access and prevent sensitive information leakage. Our services include designing security policies, implementing a firewall, and training the organization’s IT team to manage it effectively.

✔ Intrusion Detection and Prevention Systems (IDS/IPS)

Firewalls alone are not enough to combat advanced threats. IDS and IPS systems enable the detection of suspicious activities and automatic prevention of network intrusion. SUNNET protects organizations against unknown attacks and sophisticated intrusion techniques by installing and configuring up-to-date IDS/IPS. By analyzing traffic patterns, we continuously identify potential attacks and take preventative measures.

✔ Setting up and managing virtual private networks (VPNs)

Creating a secure VPN allows your organization’s employees to access internal network resources remotely and securely. SUNNET VPN services include designing, setting up, and managing virtual private networks with secure protocols such as IPSec and SSL. With our solutions, you can create encrypted and stable connections for your organization’s users and branches and ensure communication security.

✔ Enterprise antivirus and anti-malware services

SUNNET’s enterprise antivirus software provides centralized and unified management to identify, quarantine, and remove viruses, ransomware, and other types of malware on all network clients and servers. Automatic threat database updates and complete device security status reports are the main features of this service, which significantly increases the security level of your organization’s network.

✔ Network Security Monitoring & SIEM

Continuous network monitoring and security event analysis using SIEM (Security Information and Event Management) systems allows you to identify threats before an attack occurs. By installing and configuring SIEM solutions, SUNNET provides organizations with real-time reporting of user and device behavior, log collection, and anomaly detection. These services help security teams respond faster and minimize damage.

✔ Penetration Testing and Vulnerability Assessment Services

Penetration Testing helps organizations identify their security weaknesses before real attackers do. By conducting structured penetration tests, using specialized tools such as Nessus and Metasploit, and simulating real attacks, SUNNET experts prepare a detailed report of network vulnerabilities and provide remediation solutions. This service is provided periodically or based on the organization’s needs.

✔ Consulting, training, and providing valid security licenses

Network security is not limited to installing equipment; consulting and training play an important role in organizational readiness. SUNNET provides specialized consulting services for designing and improving the security structure, conducting training courses for IT teams, and providing master licenses for security products from reputable international brands such as Fortinet, Kaspersky, ESET, and Sophos. These services help organizations stay up-to-date and ready to deal with cyber threats.

Types of network security threats and effective methods to deal with them

As technology advances and devices and systems become more connected to the Internet, network security threats have become more complex and widespread. To effectively protect network infrastructure, organizations need to be familiar with these types of threats and take smart steps to prevent and combat them. The following table lists some of the most common security threats and suggested solutions to combat them:

Countermeasures	Description	Threat type
Using up-to-date antivirus and anti-malware, restricting access, updating the operating system and software	It includes viruses, Trojans, worms, and spyware that enter the system with the aim of destroying, stealing, or manipulating information.	Malware
Staff training, using suspicious email filters, two-factor authentication (2FA), and checking URLs before clicking.	Sending fake emails or messages aimed at deceiving users into revealing sensitive information such as passwords or banking details.	Phishing Attacks
Using smart firewalls, dedicated DDoS protection equipment, and collaborating with cloud protection services.	Sending traffic to the server to keep it out of the reach of legitimate users	DDoS Attacks
Implementing strong firewalls, using intrusion detection/prevention systems (IDS/IPS), and enforcing strong authentication.	Unauthorized access to network resources and information through security vulnerabilities.	Network intrusion
Regular backups, avoiding opening unknown files, using anti-ransomware software, and data recovery policies	Locking or encrypting sensitive information and demanding ransom to restore access	Ransomware
Using strong encryption (SSL/TLS), VPN connections, and mutual authentication	Eavesdropping or altering information during transmission between two parties	Man-in-the-middle (MITM) attacks
