A next-generation firewall is a part of the third generation of firewall technology, combining a traditional firewall with other network device filtering functions, such as an application firewall using in-line deep packet inspection, an intrusion prevention system.
Sandboxing refers to a method in which you use an isolated environment, or a “sandbox,” for testing. Within the sandbox, you can initiate the execution of a suspicious program or a Uniform Resource Locator (URL) that may be attached to an email. After you access the URL, execute the program or click on the attachment, and you can observe what happens.

If all traffic is unknown to firewall then and the virus is in file and due to ssl we can't decrypt ,
then how firewall understand that this is unknown viruses traffic we have to send cloud
Or
entair traffic is going to send cloud ? Apart from know traffic

[@imedita]

In a scenario where all traffic is unknown to the firewall and the virus is contained within a file that cannot be decrypted due to SSL encryption, the firewall may face challenges in identifying the presence of the virus. Firewalls typically inspect network traffic and analyze packet-level information to detect and prevent unauthorized or malicious activities.
However, in cases where traffic is encrypted using SSL, the firewall may not be able to inspect the content of the encrypted packets. This is because SSL encryption ensures the confidentiality and integrity of data being transmitted between the client and the server.
In such situations, firewalls often rely on other mechanisms to identify potential threats. These can include:
Behavioral Analysis: The firewall may monitor network behavior patterns and look for anomalies that indicate malicious activity. Unusual traffic patterns, high volumes of data transfers, or suspicious communication behavior could trigger alerts.
Reputation-based Systems: Firewalls can maintain a database of known malicious IP addresses, domains, or URLs. If traffic is originating from or heading towards these blacklisted entities, the firewall can take action accordingly.
Heuristic Analysis: Firewalls can employ heuristic techniques to detect potential threats. This involves looking for patterns or behaviors that resemble known attack vectors or malware characteristics. This method is not foolproof, as it may generate false positives or false negatives.
Intrusion Detection/Prevention Systems (IDS/IPS): IDS/IPS systems can be integrated with firewalls to provide additional security measures. These systems can analyze network traffic for known attack signatures, abnormal behaviors, or exploit attempts. If suspicious activity is detected, the IDS/IPS can trigger alerts or take appropriate action.
If the firewall determines that the traffic contains potential threats, it can forward the information to a cloud-based security service for further analysis. Cloud-based security services often leverage advanced threat intelligence, machine learning algorithms, and vast datasets to identify and respond to emerging threats.
