Backend & CI/CD Hardening
We engineer zero-trust backend architectures, high-throughput memory-safe microservices in Rust and Go, and cryptographically attested CI/CD pipelines to eliminate unauthorized state mutations, supply chain injections, and secret exfiltration.

How It Works

Threat Modeling & Attack Surface Audit
We dissect network topographies, trust boundaries, ingress controllers, and IAM roles to map out lateral movement paths and privilege escalation vectors.

Zero-Trust Perimeter & Gateway Enforcement
We configure mTLS, rate-limiting policies, WAF rules, and cryptographic payload validation layers to isolate the internal network from untrusted traffic.

Runtime Hardening & Sandboxing
Microservices are refactored into memory-safe runtimes with strict seccomp profiles, capability dropping, and micro-segmentation policies.

Pipeline Attestation & Supply Chain Security
We lock down deployment pipelines with ephemeral runners, automated dependency scanning, cryptographic artifact signing, and zero-trust deploy gates.

Live Telemetry & Invariant Monitoring
We deploy low-overhead kernel and application probes to continuously monitor process execution, socket bindings, and anomalous memory spikes.

Case Studies

Zero-Trust Gateway for Financial Clearing House
Architected an end-to-end memory-safe Rust API gateway processing over 45,000 requests per second. Integrated mTLS authentication, hardware-backed token verification, and automated rate-limiting to eliminate unauthorized transaction injections.

What Our Clients Say
"Zanvexis rebuilt our entire API gateway in Rust with hardware-level secret management. We achieved sub-millisecond response times while eliminating an entire class of vulnerability vectors."

"Their CI/CD hardening and automated binary signing gave our institutional clients verified mathematical proof of software integrity before every production deployment."

Frequently Asked Questions
QWhy does Zanvexis mandate memory-safe languages like Rust for backend systems?
Memory corruption vulnerabilities (such as buffer overflows, use-after-free, and race conditions) represent over 70% of critical security exploits in low-level backends. Writing core microservices in Rust guarantees memory safety at compile time without garbage collection latency spikes.
QHow do you secure secrets within CI/CD pipelines?
We eliminate static long-lived credentials. All pipeline jobs authenticate via OpenID Connect (OIDC) to ephemeral identity providers (like HashiCorp Vault or AWS KMS), requesting short-lived, single-use tokens that expire immediately upon job completion.
QWhat is SLSA compliance and why does it matter for enterprise software?
Supply-chain Levels for Software Artifacts (SLSA) is a security framework that prevents tampering during build and release processes. We implement SLSA Level 3+ standards, ensuring that every deployment artifact is generated on isolated runners with cryptographic provenance.
QHow does the zero-trust gateway handle sudden traffic spikes during a DDoS attack?
Our gateway employs eBPF and kernel-level packet inspection combined with Envoy proxy modules to drop unauthorized payloads before they consume user-space memory, maintaining line-rate processing even under adversarial load.
