Firewalls
Firewalls serve as a barrier between trusted internal networks and untrusted external networks. They can be either hardware or software-based and help prevent unauthorized access to or from a private network.
Intrusion Prevention Systems (IPS)
Like IDS, IPS tools detect potential security breaches but also take preventative action, often by blocking network traffic from the suspicious source.
Virtual Private Networks (VPN)
VPNs create a secure and encrypted connection between a user's device and the network they connect to, thereby securing data in transit.
Data Loss Prevention (DLP)
DLP technologies stop users from sending sensitive data outside the network. They can identify, monitor, and protect data in use, data in motion, and data at rest.
Antivirus and Antimalware Software
These tools help prevent, detect, and remove malicious software, such as viruses, trojans, ransomware, and worms.
Network Segmentation
This technique splits a computer network into subnetworks, each being a network segment, to increase security and efficiency.
Network Access Control (NAC)
NAC solutions only allow compliant and trusted devices, whether managed or unmanaged, onto the network.
Security Information and Event Management (SIEM)
SIEM tools enable IT teams to log, monitor, and analyze activity in real-time across their networks.
Network Encryption
Network encryption is used to protect information by converting it into an unreadable format.
Wireless Security
This is essential for protecting wireless networks and can include tools and protocols such as WPA3.
Network Behavior Anomaly Detection (NBAD)
NBAD continuously monitors a network for unusual events or trends.
Zero Trust Network Access (ZTNA)
ZTNA solutions allow for secure access to specific applications based on user identity and context, effectively removing the traditional concept of a network perimeter.
Secure Access Service Edge (SASE)
SASE combines network security functions with wide area networking (WAN) capabilities to support the dynamic, secure access needs of organizations. These can include capabilities such as SD-WAN, firewall as a service, secure web gateway, and ZTNA.
