This chapter lists features and enhancements introduced in each of the FortiADC releases.
FortiADC now supports HTTP/HTTPS filters for SAP system. New filters can be used with or without AS virtual host.
In SAP Connector configuration, you can enter IP address and FQDN or hostname for the server. If hostname is used, DNS-suffix (DNS name of the SAP system) is required.
Cloud-init is supported by FortiADC on Azure Platform. License for BYOL type and FortiADC CLI commands can be specified in the custom data so that FortiADC-VM can be deployed with preset configurations.
Automation Stitches can be used to automate certain actions in response to certain triggers. This includes sending alert emails in response to specific events, and allows for far more granular log-based alerting that Alert Emails configured under Log & Report.
Each Automation pairs an event trigger and one or more actions, which allows you to monitor your network and take appropriate action when the Security Fabric detects a threat. You can use Automation stitches to detect events from any source in the Security Fabric and apply actions to any destination.
For example, you can create the following Automation stitches:
Ban a compromised host’s IP address on FortiGate
Increase Server Capacity due to High Latency/Load
Increase Server Security during Web Attack
There are CLI changes relating to Automation. See "What's New" in FortiADC CLI Reference.
A matched part is added to WAF logs to indicate which part of the HTTP request/response has triggered the WAF event. This is helpful to identify the details for the attacks.
FortiADC1200F, 2200F, and 4200F are introduced in 6.1.1.
For more infomation, see FortiADC datasheets.
In L4 VS Direct Route deployment, you can set the VS IP on the loopback interface of real servers and publish the service on this IP.
In this mode, the service state on the real server (loopback interface IP) can't be detected. It is supported to forward the health check request to the real server as next hop, with the destination IP of VS IP. The real server will reply the request via routing just as it responses to the client's request.
Normally when the real server is set to maintain mode, all new sessions will be routed to other active real servers, which may cause re-authentication in some deployment.
To solve this issue, an option is added to source address persistence. It allows new sessions to be persisted to the real server even when it is set to maintain mode.
Lua script now supports for other L7 VS than HTTP VS, so that the actions that are not currently supported by built-in features can be performed. For example, you can use this script to manipulate request/response for Radius, ISO8583, etc.
For more information, see FortiADC Script Reference Guide.
The following enhancements are made in GUI:
SSL proxy statistics graphs are moved from Dashboard to FortiView (SSL proxy mode)
Password policy is displayed when admin password is created or edited.
New design for interface page to show interface status/avail.
FortiADC 6.0.0 offers the following new features:
- The default down retry value has been changed from 1 attempt to 3 attempts, allowing for more tries before determining the server status to be down. The default interval time has been changed from 10 seconds to 5 seconds, and the default timeout has been changed from 5 seconds to 3 seconds.
- Interface information displayed when hovering over the port column .
- Change the port status from Up/Down to Enabled/Disabled, and only use the Up/Down for the link stat in availability.
- Remove some columns to make the interface page more concise.
- blacklist/whitelist changed to blocklist/allowlist
- master/slave changed to primary/secondary
FortiADC 6.0.0 offers the following new features:
Kubernetes Connector (Ingress controller)
The FortiADC Kubernetes connector is a FortiADC built-in connector, which is used to sync Kubernetes objects (service, nod, pod) and update it to VS automatically.
Note: The K8s connector currently works with K8s Service API version 1 only. Support is not guaranteed for later versions.
MSSQL load balance
Support load balancing for MSSQL servers in the scenario where one primary replica and multiple secondary replicas are used. It allows FortiADC to forward the read SQL requests (e.g. “select”) to multiple secondary servers and other write requests to the primary server.
NTLM is a suite of Microsoft security protocols intended to provide authentication, integrity, and confidentiality to users. This authentication mechanism allows clients to access resources using their Windows credentials, and is typically used within corporate environments to provide single sign-on functionality to intranet sites.
HTTP Form based authentication with FortiToken cloud
FortiToken Cloud offers two-factor authentication as a service to Fortinet customers. This feature support the authentication with FortiToken Cloud for the HTTP virtual server access.
Error page enhancement
Supports more code statuses for error page (in addition to 502), so now the error page can be used for any error.
Update TLS1.3 cipher list, and have more configuration checks for TLS1.3 settings
Keep client address for L7 DNS virtual server
In some deployments for security/audit reasons, backend real server requires the original client address. In this feature we can keep client address unchanged when forwarding the DNS request to real server.
CAPTCHA action support for WAF and DDoS
CAPTCHA(Completely Automated Public Turing test to tell Computers and Humans Apart) is a type of challenge–response test used to distinguish human from machine input, typically as a way of thwarting spam and automated extraction of data from websites. It can be used in WAF and DDoS module as a new action.
API security gateway
The feature provides an API gateway for backend API services. It processes essential checks to API requests, such as user authentication, rate limiting, source IP limiting, request method/header limiting, and header attaching, to mitigate the attacks to backend API services.
HTTP headers security
Some HTTP headers are designed to provide another layer of security to mitigate web attacks and security vulnerabilities. This feature allows FortiADC to attach these HTTP security headers while forwarding HTTP traffic. These HTTP security headers include content-security-policy, x-xss-protection header, HTTP strict-transport-security (HSTS), x-frame-options, x-content-type-options.
Support X-HTTP-Method-Override in Request Method Rule
There exists attacks that use a trusted HTTP methods such as GET or POST, but adding HTTP headers such as XHTTP-Method, X-HTTP-Method-Override, or X-Method-Override to bypass the HTTP method restriction rules are applied by FortiADC. This feature allows FortiADC to check these HTTP headers while checking HTTP method rules to avoid such security bypassing.
New Security Fabric provides a visionary approach to integrate internal and external security connectors, including Central Manager, FortiSandbox, and FortiGSLB.
FortiADC offers external connectors for 3rd party applications.
The following external connector categories are available in the Security Fabric: Private SDN and Authentication.
Splunk App is an application runs on Splunk platform to analyze and display the information from the collected log data.
For FortiADC, customer configure the Splunk Connector to the Splunk Server, and then get all the customized graphs from the Splunk App
FortiToken Cloud support for administrator
FortiADC provide administrator login management with FortiToken Cloud as a two-factor authentication.
Add secure flag when use HTTPs to access ADC to avoid cookie leaking
Secure enhancement to enable secure flag in HTTPS response prevents authentication cookie from leaking to HTTP connections. Added https-redirect option to redirect all HTTP connection to HTTPS, enabled by default.
HA MAC address changes to management interface MAC
We allow customers to configure different virtual MAC for HA interface, which previously may have caused MAC issues on the peer switch. To avoid these issues, we reuse the same MAC of the physical interface.
- Upgrade FortiGuard authentication method to be more secure
- New FortiGate-like theme
More cohesive information in FortiView
Show all statistics of Real Servers of Virtual Server in one form.
Show all the values of each real server of each virtual server, not using the graph
WAF pages enhancement
WAF profile and signature pages redesign
FortiADC 6.1.2 offers the following new features:
Configure real server by FQDN
In some customer deployments, the real servers (RS) change their IP address due to autoscaling, upgrades, etc, which requires RS IP settings to be changed in RS pool accordingly.
This feature will support configuring FQDN for a real server. FAD will query the DNS server periodically and once the IP address changes, it will resolve the new IP address for this real server automatically.
Customizable authentication form for Form Based Authentication
Beyond the default authentication form, customers can also upload a user-defined login page for all the form-based authentications. Customers are able to define their own authentication portal.
Manage HTTP persistence via script

This chapter lists features and enhancements introduced in each of the FortiADC releases.
FortiADC (Undefined variable: FortiADCVariables.VersionSubtitle56) offers the following new features:
IPS service will allow you to protect your virtual servers from the latest network intrusions by actively detecting and blocking external threats before they can reach potentially vulnerable devices. The combination of real-time threat intelligence updates and thousands of existing intrusion prevention rules delivers the industry’s best IPS protection.
A distributed denial-of-service (DDoS) attack is a malicious attempt to disrupt the normal traffic of a targeted server, service or network by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic. FortiADC support 2 layers DDoS protection:
1. Networking DoS protection
The attacker sends a huge volume of large or uncompleted IP fragmentation packets to the victim, to exhaust the victim’s resources. The IP fragmentation protection here limits the total IP fragmentation memory size to avoid memory exhaustion.
TCP SYN flood
By enabling SYN-Cookie to all the SYN packets that exceed the threshold, the system will drop all the fake SYN packets sent to the virtual server.
TCP slow data flood
The attacker uses very slow traffic to consume all the target server’s resources; it is difficult to distinguish it from normal traffic. This protection will detect this type of attack by dynamically probing client 0 windows; if it comes in "last" several times, the FortiADC will rest this connection on server.
2. Application DoS protection
HTTP access limit
Limits the amount of HTTP requests-per-second from a certain IP.
HTTP connection flood
Limits the number of TCP connections with the same session cookie.
HTTP request flood
Limits the number of HTTP requests-per-second with the same session cookie.
FortiADC web application firewalls provide advanced features that defend web applications from known and zero-day threats. FortiADC offers a complete security coverage for your web-based applications from the OWASP Top 10 and many other threats.
1. Signature DB enhancement
Enhances WAF engine to more efficiently scan for packets, also significantly increasing the detection rate.
2. New WAF signature wizard on GUI
Helps customer configure the WAF signature profile.
3. WAF Action enhancement
Besides deny and pass, supports 2 more actions for all WAF modules: Redirect and Block period.
4. CSRF protection
A cross-site request forgery (CSRF) is an attack that exploits the trust that a site has in a user's browser to transmit unauthorized commands.
To protect back-end servers from CSRF attacks, FortiADC has two lists:
- Web pages to protect against CSRF attacks – for insert JS
- URLs found in the requests that the pages generate – for Token/cookie validation
5. Input validation
FortiADC provides advanced validation of input fields, including parameter validation, hidden field validation and file security. This function will verify the user input from scan points like URL parameter, HTML form, hidden fields, upload file. If the format isn't correct or other attacks exist, the request will be blocked.
6. Brute force detection
FortiADC can prevent brute force login attacks. Brute force attackers attempt to penetrate systems by the sheer number of clients, attempts, or computational power, rather than by intelligent insight or advance knowledge of application logic or data.
7. Data loss protection
The data loss prevention (DLP) feature allows FortiADC to prevent information leaks, damages and loss.
It provides desensitization and warning measures for sensitive information leaks on websites (SSN numbers, and credit card information) and the leakage of sensitive keywords.
8. Cookie Security
HTTP cookie is a small piece of data sent from a website and stored in the client’s computer. In some cases, it will store some sensitive date inside, e.g. password.
If the client sends out the request that Fortiadc doesn’t recognize, it will take corresponding action (alert/ deny/ period-block/ remove-cookie).
9. Page anti-defacement
The anti-defacement features monitor your websites for defacement attacks. If it detects a change, it can automatically reverse the damage.
This feature monitors the modification of customer's specified page; once the modification is consider as abnormal, the specified action will be triggered, such as "restore changed page," "send email," "acknowledge changed page," or "just record log."
10. Web scraping detection
FortiADC provides an advanced access control for customers who want to have agility within web application (specific IP, files, connections).
FortiADC checks the http header content-type and the response code; if it matches the occurrence limit and is over the match percentage, it will detect it as web scraping.
11. Web vulnerability scanner enhancement
Able to add URL into the exception list.
Supports form-based login
Supports form-based login for web servers.
FortiADC firewall now supports address book in the policy.
Two-factor authentication is a type of multi-factor authentication. It is a method of confirming users' claimed identities by using a combination of two different factors. FortiADC can use script to do 2-step verification with FortiToken and Google Authenticator.
Adds more detailed report for each health check failure log, so the customer can quickly grasp why the health check failed and what happened on the real server.
Supports CLI “diagnose debug slb_hc_status” to show the health check status for all the SLB pool.
The BYOL FortiADC images are listed on the AWS/Azure/OCI cloud marketplace now, and the customer can deploy them through these cloud marketplaces.
Ansible is an automation platform that makes your applications and systems easy to deploy. FortiADC modules allow the customer to automatically initiate the configuration or manage the configuration on any kind of FortiADC devices, including physical devices, VM in hypervisor or cloud.
Both encrypted and unencrypted private key are allowed to be exported; it is necessary for the customer to move FortiADC hosted HTTPS services.
Besides UDP-based syslog server, FortiADC supports TCP/TCP-SSL based remote syslog servers in case the customer needs more confidential security for the logs.
In some multiple vdom deployments, some non-root vdom administrators may need to send logs to global syslog server in case of networking issues in their vdom. This feature allows the global syslog server to be shared among all non-root vdoms.
Shows all the LLB group/member status, and GSLB host status, by a topology graph on FortiView.
FortiADC support 2 new hardware models:
• FortiADC 300F
• FortiADC 400F
For more info on new hardware, please review the FortiADC Datasheet.
FortiADC 5.2.3 offers the following new features:
This option will allow the FortiADC to serve the request and send back the response even if the client closes the output channel.
In some cases, the client may close the output channel even after sending out the request; but at the same time the client will be waiting for a response. If this option is disabled, the FortiADC will abort, and will not serve the request anymore once it receives notice that the client has closed the channel. This may cause clients tocomplain of failures.
In SSL forward deployment, the second ADC (HTTP->HTTPS) may not forward any SNI to backend Real Server, causing failure for some servers. In this feature, if “SNI forward flag” in server SSL is enabled, it will forward host in HTTP header as SNI to Real Server by default. If there is no host in HTTP header, it will forward the ssl-sni settings as SNI to Real Server.
FortiADC 5.2.2 offers the following new features:
Memory Restriction has been removed for all BYOL VM on AWS/GCP/Azure/OCI/Aliyun cloud platforms.
Support PROXY protocol for HTTP/HTTPS virtual server, to pass original client information, such as the client IP address, to the backend proxies or servers.
See the PROXY protocol reference.
FortiADC 5.2.1 offers the following new features:
The Fortinet Security Fabric delivers broad protection and visibility to every network segment, device, and appliance, whether virtual, in the cloud, or on-premises. After adding FortiADC to Security Fabric, it will show the real-time visibility of FortiADC, including Virtual Server status, and various statistics.
The Web Cache Communication Protocol (WCCP) allows the server to be enabled for transparent redirection to discover, verify, and advertise connectivity to one or more web-caches. You can configure FortiADC as a WCCP server to redirect HTTP/HTTPS VS traffic to 3rd party device for caching or more security inspection.
Allows FortiADC DNS service to send zone notification to secondary servers, and also receive and process incoming zone transfer message from secondary servers.
Customer can provide a public IP address for the GLB discovered virtual server address, which is necessary for the deployment which whose server is behind NAT.
The Radius Change of Authorization (CoA), defined in RFC5176, provides a mechanism to dynamically change the attributes of an AAA session after the user or device is authenticated. By this feature, FortiADC can process CoA messages from external Radius server and send the traffic to the right dynamic authorization server through persistence.
Certificate Revocation List Distribution Point (CRLDP) defines how to get a CRL file from a distribution point, which is LDAP URI or HTTP/HTTPS URL, to verify client certificate.
Collect statistics like RPS, CPS, transaction latency, session duration, throughput per virtual server/real server, and generate reports including these metrics.
Usually if you enable traffic log, there will be a huge volume of traffic logs. In this situation, to browse or filter traffic log is much too slow; with this feature, we redesign the traffic log browser page to show and locate logs quickly.
FortiADC 5.2.0 offers the following new features:
Supports specific routing (schedule pool, persistence, method) by source address
Prior to 5.2.0, all connections are cleared if RS is detected to be exceeding the threshold; now, however, when RS exceeds the threshold, the old connection is kept while not dispatching new connections
The ADFS Proxy is a service that brokers a connection between external users and internal ADFS servers, also called a Web Applicaition Proxy (WAP). More and more ADFS require the proxy to support MS-ADFSPIP (ADFS Proxy Integration Protocol) which involves client certificate authentication between proxy and ADFS, trust establishment, header injection, and more. FADC from 5.2.0 has support for MS-ADFSPIP.

JSON Schema provides a contract for what JSON data is required for a given application and how to interact with it. This feature supports the user uploading a JSON schema to validate JSON data, just like the XML validation that we had before.
Now possible to upload a list of IPs or CIDRs to the IP reputation black list, then blocking them by enabling "IP reputation" in Application Profile for VS.
New function to show/delete quarantined files on FortiADC by GUI (Network Security -> Quarantine Monitor)
Now supports uploading and deploying VM images on these public cloud platforms; you can easily extend existing FortiADC services to the cloud.
In HA AP scenarios, the secondary device will become primary if the primary device is down, but after the former primary comes back, there will be a new switchover (the former primary takes the primary role, and the current primary, the former secondary, switches back to secondary). This switchover is unnecessary and may impact traffic, so the enhancement here is to avoid doing the switchover after the former primary comes back.
Before, in order to submit information to Help Support, the customer needed to gather files from different places; now, this debug enhancement automatically collects all necessary debug information into one file, so it's easier to submit to Help Support.
FortiADCManager is a central management tool to manage all your FortiADC devices in your network, providing visibility and the ability to create/edit server load balance configurations for all FortiADC devices.
