In many environments, TLS termination is still treated as managing a certificate file, a private key and a cipher list. Modern application delivery, however, requires TLS to be thought of together with SNI, ALPN, TLS 1.3, HTTP/2, HTTP/3, legacy client compatibility, session ticket policy, mTLS, certificate renewal and detailed log visibility. When these pieces are managed in isolation, both security posture and operational complexity suffer.
In enterprise environments, legacy systems and modern applications run side by side on the same ADC. One service may require TLS 1.0 or 1.1 compatibility while another demands TLS 1.3, HTTP/2 or HTTP/3 behavior. If these requirements are bound to a single device-wide setting, either legacy services break or the security level of modern services is unnecessarily lowered.
Certificate operations are also a recurring risk area. When the team that owns the certificate and the team that manages the ADC are different, every renewal becomes a change request and every chain error becomes a potential outage. If PFX, PEM, passphrases, key types, CNs, DNS names and validity dates are not centrally validated, the renewal process becomes fragile.
Long-term confidentiality is the new risk layer. Traffic that appears encrypted today can be recorded and targeted later with greater decryption capacity. That is why a modern TLS layer must carry not only today's cipher compatibility but also forward-looking defense options such as post-quantum hybrid key exchange within the service profile.
TR7 SSL/TLS Acceleration meets this need: it moves TLS beyond file-based configuration and turns it into a per-service security profile, certificate lifecycle and modern cryptography readiness layer.
TR7 manages TLS termination together with a certificate pool, service profiles, SNI selection and deterministic configuration generation.
TLS minimum and maximum version, cipher template, manual cipher list and TLS ticket policy are all defined within the same service profile. Different TLS policies can be applied independently on the frontend and the backend.
Multiple certificates can be placed on the same service entry. The correct certificate is selected based on the SNI value; wildcard, multi-domain and dual ECDSA/RSA scenarios can all be managed on the same port.
CSR creation, certificate parsing, key type detection, passphrase operations and PFX↔PEM conversion are all handled inside TR7. Validity dates, CN, DNS names, algorithm and key length are tracked as metadata on the certificate object.
TR7 handles modern TLS capabilities — TLS 1.3, HTTP/3 over QUIC and ML-KEM-based hybrid key exchange — together with service policy. This architecture helps manage both current performance expectations and long-term confidentiality risks in the same layer.
SSL/TLS Acceleration combines per-service TLS security with certificate operations, backend encryption and modern protocol support.
TR7 manages minimum and maximum TLS version within the service profile. Broader compatibility can be applied to legacy services while stricter TLS 1.2+ or TLS 1.3 policy is enforced on modern API and web services — all on separate service entries. No device-wide "all old or all new" constraint is imposed. Each service is configured according to its own risk, compliance and client requirements.
Multiple certificates can be defined on the same port and service. The correct certificate is selected based on the SNI value sent by the client. Different domains, wildcard certificates or ECDSA and RSA certificates for the same domain can coexist. This design simplifies multi-domain publishing without requiring separate VIPs or separate ports.
TR7 can manage HTTP/2 and HTTP/1.1 behavior via ALPN within the service profile. HTTP/3 over QUIC support reduces connection setup latency and head-of-line blocking effects, particularly in mobile and lossy networks. HTTP/2 fallback preserves backward compatibility. The service can serve different generations of clients within the same publishing model.
TR7 supports onlySecure, tls13, old, general, strictSecure, strictOld, strictHardware and hardware templates, as well as manual cipher list definition. Security teams can select standard compliance profiles; operations teams can manually adjust specific cipher behavior in exceptional cases. This model moves cipher management from long and fragile text lists toward profile selection. When manual mode is needed, the operator retains full control.
TR7 provides post-quantum readiness through ML-KEM-based hybrid key exchange support. This approach combines classical key exchange with a post-quantum KEM, offering a transition model between client compatibility and long-term confidentiality. Sensitive enterprise traffic can be moved to a stronger cryptographic foundation today against the "harvest now, decrypt later" risk. This readiness is especially important in sectors such as finance, government and healthcare where data must remain confidential for years.
TR7 can terminate TLS between the client and the ADC while re-encrypting the connection between the ADC and the backend with TLS. Backend mTLS settings — verify required, CA file and client certificate — can be bound to the service profile. This model maintains encrypted communication on the internal network while allowing inspection at the edge. Different TLS version and cipher policies can be applied independently on the frontend and the backend.
TLS protocol version, ALPN status and client handshake behavior are not just connection details. Signals such as a deprecated TLS version or the absence of ALPN can be evaluated as additional indicators in bot and risk analysis. The TLS layer thus produces data not only about encryption but also about client quality and automation behavior. These signals enrich security decisions.
TR7 can extract DNS names, CN, issuer, validity dates, algorithm and key length from certificates. RSA and EC key types are distinguished; passphrase addition or removal is supported. PFX/P12 files can be parsed into PEM structure or packaged in the reverse direction. These capabilities remove the dependency on external tools for certificate operations.
TLS operations are managed together with certificate parsing, key conversion, PFX/PEM processing, diff-based reload, curve compatibility checks and expiry notifications.
When a certificate is loaded, DNS names, CN, issuer, validity start, expiry date, algorithm and key length are extracted. If one parse method fails, an alternative parse path can be engaged. Certificate metadata is therefore managed by actual content, not just by file name.
Whether a private key is RSA or EC is detected automatically. EC and RSA key operations are handled according to their respective requirements. Passphrase addition, removal and format compatibility are managed as part of the certificate operation.
PFX/P12 bundles can be parsed into their key and certificate components. When needed, PEM contents can be converted back into PFX format. This makes it straightforward to standardize the different certificate delivery formats that different organizations use — all within TR7.
The same input always produces the same configuration; a reload is triggered only when a genuine difference is detected. Unnecessary service disruption is avoided when certificates or TLS profiles change. Existing connections are preserved while new connections are served with the updated TLS behavior.
Curve names are normalized to reduce compatibility differences. Unsupported or removed curve usage can be blocked. This check helps keep the certificate and TLS profile aligned with modern cryptography expectations.
The certificate expiry date is tracked as metadata. Notifications can be configured to fire 30 days before expiry by default. This helps prevent service outages caused by unnoticed certificate expiration.
E-commerce teams can apply TLS 1.2+ policy, a secure cipher template, closed ticket behavior and regular certificate tracking within a single service profile. Which TLS profile is in use on which services can be viewed centrally for compliance audits.
In banking environments, a service requiring legacy clients and an internet banking application using TLS 1.3 can be published on the same TR7 ADC with different profiles. Legacy compatibility does not lower the security level of modern services.
Finance, government and healthcare organizations can move sensitive traffic to a stronger cryptographic foundation against future decryption risks using ML-KEM hybrid key exchange. This scenario provides cryptographic readiness today for data that must remain confidential for years.
Security teams can terminate TLS between the client and TR7 while re-encrypting the connection between TR7 and the backend with TLS. mTLS and CA validation bring internal network traffic under the security policy as well.
