Compatibility
Before you upgrade or reimage, make sure the target version is compatible with your deployment. If you cannot upgrade or reimage due to incompatibility, contact your Cisco representative or partner contact for refresh information.
For compatibility information, see:
Features
For features in earlier releases, see Cisco Secure Firewall Management Center New Features by Release and Cisco Secure Firewall Device Manager New Features by Release.
 Note |
Patches are largely limited to urgent bug fixes: Bugs. If a patch does include a feature or behavior change, it is described in the section for the "parent" release. |
Upgrade Impact
A feature has upgrade impact if upgrading and deploying can cause the system to process traffic or otherwise act differently without any other action on your part. This is especially common with new threat detection and application identification capabilities. A feature can also have upgrade impact if upgrading requires that you take action before or after upgrade to avoid an undesirable outcome; for example, if you must change a configuration. Having to enable a new setting or deploy a policy post-upgrade to take advantage of a new feature does not count as upgrade impact.
The feature descriptions below include upgrade impact where appropriate. For a more complete list of features with upgrade impact by version, see Upgrade Impact Features.
Snort 3
Snort 3 is the default inspection engine for threat defense.
Snort 3 features for management center deployments also apply to device manager, even if they are not listed as new device manager features. However, keep in mind that the management center may offer more configurable options than device manager.
Important |
If you are still using the Snort 2 inspection engine, switch to Snort 3 now for improved detection and performance. Snort 2 will be deprecated in a future release and will eventually prevent threat defense upgrade. |
Intrusion Rules and Keywords
Upgrades can import and auto-enable new and updated intrusion rules and preprocessor rules, modified states for existing rules, and modified default intrusion policy settings. If a newer intrusion rule uses keywords that are not supported in your current version, that rule is not imported when you update the SRU/LSP. After you upgrade and those keywords become supported, the new intrusion rules are imported and, depending on your IPS configuration, can become auto-enabled and thus start generating events and affecting traffic flow.
For details on new keywords, see the Snort release notes: https://www.snort.org/downloads.
FlexConfig
Upgrades can add web interface or Smart CLI support for features that previously required FlexConfig. The upgrade does not convert FlexConfigs. After upgrade, configure the newly supported features in the web interface or Smart CLI. When you are satisfied with the new configuration, delete the deprecated FlexConfigs.
The feature descriptions below include information on deprecated FlexConfigs when appropriate. For a full list of deprecated FlexConfigs, see your configuration guide.
 Caution |
Although you cannot newly assign or create FlexConfig objects using deprecated commands, in most cases existing FlexConfigs continue to work and you can still deploy. However, sometimes, using deprecated commands can cause deployment issues. |
REST API
For information on what's new in the REST API, see the Secure Firewall Management Center REST API Quick Start Guide or the Cisco Secure Firewall Threat Defense REST API Guide.
Cisco Success Network Telemetry
Cisco Success Network sends usage information and statistics to Cisco, which are essential to provide you with technical support. For information on what's new with telemetry, see Cisco Success Network Telemetry Data Collected from Cisco Secure Firewall Management Center.
Language Preferences
If you are using the web interface in a language other than English, features introduced in maintenance releases and patches may not be translated until the next major release.

7.6.0 |
7.6.0 |
Individual interfaces are normal routed interfaces, each with their own local IP address used for routing. The main cluster IP address for each interface is a fixed address that always belongs to the control node. When the control node changes, the main cluster IP address moves to the new control node, so management of the cluster continues seamlessly. Load balancing must be configured separately on the upstream switch. Restrictions: Not supported for container instances. New/modified screens: See: Clustering for the Secure Firewall 3100/4200 and Address Pools |
|
Deploy threat defense virtual clusters across multiple AWS availability zones. |
7.6.0 |

Access Control: Threat Detection and Application Identification |
|||
|
Snort ML: neural network-based exploit detector. |
7.6.0 |
7.6.0 with Snort 3 |
A new Snort 3 inspector, snort_ml, uses neural network-based machine learning (ML) to detect known and 0-day attacks without needing multiple preset rules. The inspector subscribes to HTTP events and looks for the HTTP URI, which in turn is used by a neural network to detect exploits (currently limited to SQL injections). The new inspector is currently disabled in all default policies except maximum detection. A new intrusion rule, GID:411 SID:1, generates an event when the snort_ml detects an attack. This rule is also currently disabled in all default policies except maximum detection. |
|
Bypass EVE block verdict for trusted traffic. |
7.6.0 |
Any with Snort 3 |
You can now bypass EVE (encrypted visibility engine) block verdicts for known trusted traffic, based on destination network or EVE process name. Connections that bypass EVE in this way have the new EVE Exempted reason. New/modified screens:
|
|
Easily bypass decryption for sensitive and undecryptable traffic. |
7.6.0 |
Any |
It is now easier to bypass decryption for sensitive and undecryptable traffic, which protects users and improves performance. New decryption policies now include predefined rules that, if enabled, can automatically bypass decryption for sensitive URL categories (such as finance or medical), undecryptable distinguished names, and undecryptable applications. Distinguished names and applications are undecryptable typically because they use TLS/SSL certificate pinning, which is itself not decryptable. For outbound decryption, you enable/disable these rules as part of creating the policy. For inbound decryption, the rules are disabled by default. After the policy is created, you can edit, reorder, or delete the rules entirely. New/modified screens: |
|
QUIC decryption. |
7.6.0 |
7.6.0 with Snort 3 |
You can configure the decryption policy to apply to sessions running on the QUIC protocol. QUIC decryption is disabled by default. You can selectively enable QUIC decryption per decryption policy and write decryption rules to apply to QUIC traffic. By decrypting QUIC connections, the system can then inspect the connections for intrusion, malware, or other issues. You can also apply granular control and filtering of decrypted QUIC connections based on specific criteria in the access control policy. We modified the decryption policy Advanced Settings to include the option to enable QUIC decryption. |
|
Allow Cisco Talos to conduct advanced threat hunting and intelligence gathering using your traffic. |
7.6.0 |
7.6.0 with Snort 3 |
Upgrade impact. Upgrade enables telemetry. You can help Talos (Cisco’s threat intelligence team) develop a more comprehensive understanding of the threat landscape by enabling threat hunting telemetry. With this feature, events from special intrusion rules are sent to Talos to help with threat analysis, intelligence gathering, and development of better protection strategies. This setting is enabled by default in new and upgraded deployments. New/modified screens: System ( |
|
Access Control: Identity |
|||
|

Active: 7.6.0 with Snort 3 Passive: 7.4.0 with Snort 3 |
You can now use Microsoft Azure Active Directory (AD) realms for active and passive authentication:
We use SAML (Security Assertion Markup Language) to establish a trust relationship between a service provider (the devices that handle authentication requests) and an identity provider (Azure AD). Upgrade impact. If you had a Microsoft Azure AD realm configured before the upgrade, it is displayed as a SAML - Azure AD realm configured for passive authentication. All previous user session data is preserved. New/modified screens: New/modified CLI commands: none |
|
New connectors for Cisco Secure Dynamic Attributes Connector. |
7.6.0 |
Any |
Cisco Secure Dynamic Attributes Connector now supports AWS security groups, AWS service tags, and Cisco Cyber Vision.

Deprecated Features |
|||
|
End of support: Firepower 2110, 2120, 2130, 2140. |
— |
7.6.0 |
You cannot run Version 7.6+ on the Firepower 2110, 2120, 2130, or 2140. Although a newer management center can manage older devices, the Version 7.6 documentation only includes features supported in Version 7.6 threat defense. For features that are only supported with older devices, refer to the management center guide that matches your threat defense version. |
|
End of management support: ASA FirePOWER and NGIPSv. |
7.6.0 |
— |
You cannot manage Classic devices (ASA FirePOWER and NGIPSv) with a Version 7.6+ management center. This is because Classic devices cannot be upgraded past Version 7.0, and a Version 7.6 management center can only manage devices as far back as Version 7.1. New/modified screens: For new and upgraded management centers, Classic-specific configurations and screens are removed. This includes platform settings, NAT, syslog logging, licensing, and so on. In some cases, creating threat defense configurations is quicker because you do not have to begin by selecting a device type. |
|
Deprecated: Copy upgrade packages ("peer-to-peer sync") from device to device. |
7.6.0 |
7.6.0 |
You can no longer use the threat defense CLI to copy upgrade packages between devices over the management network.

Upgrade Impact Features
A feature has upgrade impact if upgrading and deploying can cause the system to process traffic or otherwise act differently without any other action on your part. This is especially common with new threat detection and application identification capabilities. A feature can also have upgrade impact if upgrading requires that you take action before or after upgrade to avoid an undesirable outcome; for example, if you must change a configuration. Having to enable a new setting or deploy a policy post-upgrade to take advantage of a new feature does not count as upgrade impact.
Note |
Deploying can affect traffic flow and inspection; see the appropriate upgrade guide for details: Cisco Secure Firewall Threat Defense: Install and Upgrade Guides. |
 Tip |
Features, enhancements, and critical fixes can skip releases; these skipped releases are usually short-term major versions or early maintenance releases for long-term major versions. To minimize upgrade impact, do not upgrade to a release that deprecates features. In most cases, you can upgrade directly to the latest maintenance release for any major version. |

Upgrade Guidelines for the Firepower 4100/9300 Chassis
In most cases, we recommend you use the latest FXOS build in each major version. For release-specific FXOS upgrade warnings and guidelines, as well as features and bugs with upgrade impact, see the FXOS release notes. Check all release notes between your current and target version: http://www.cisco.com/go/firepower9300-rns.
Upgrade Path
Planning your upgrade path is especially important for large deployments, multi-hop upgrades, and situations where you need to coordinate chassis, hosting environment or other upgrades.
Upgrading the Management Center
The management center must run the same or newer version as its devices. Upgrade the management center to your target version first, then upgrade devices. If you begin with devices running a much older version than the management center, further management center upgrades can be blocked. In this case perform a three (or more) step upgrade: devices first, then the management center, then devices again.
Upgrading Threat Defense with Chassis Upgrade
Some devices may require a chassis upgrade (FXOS and firmware) before you upgrade the software:
-
Secure Firewall 3100/4200 in multi-instance mode: Any upgrade can require a chassis upgrade. Although you upgrade the chassis and threat defense separately, one package contains the chassis and threat defense upgrades and you perform both from the management center. The compatibility work is done for you. It is possible to have a chassis-only upgrade or a threat defense-only upgrade.
-
Firepower 4100/9300: Major versions require a chassis upgrade.
Because you upgrade the chassis first, you will briefly run a supported—but not recommended—combination, where the operating system is "ahead" of threat defense. If the chassis is already well ahead of its devices, further chassis upgrades can be blocked. In this case perform a three (or more) step upgrade: devices first, then the chassis, then devices again. Or, perform a full reimage. In high availability or clustered deployments, upgrade one chassis at a time.
Supported Direct Upgrades
This table shows the supported direct upgrades for management center and threat defense software. Note that although you can upgrade directly to major and maintenance releases, patches change the fourth digit only. You cannot upgrade directly to a patch from a previous major or maintenance release.
For the Firepower 4100/9300, the table also lists companion FXOS versions. If a chassis upgrade is required, threat defense upgrade is blocked. In most cases we recommend the latest build in each version; for minimum builds see the Cisco Secure Firewall Threat Defense Compatibility Guide.
