Alice & Bob
Two perspectives, one vision
We build custom cybersecurity software and help companies understand and fix their security risks.
What we work on
Technically complex problems where the standard solution doesn't exist or isn't good enough.
Real profiling, instrumentation, architectural rewrites. When something is slow, we find exactly why — not approximately. Event loop bottlenecks, memory fragmentation, inefficient I/O patterns, broken concurrency models.
Adversarial attacks, prompt injection, training data extraction, model inversion, RAG pipeline poisoning, membership inference. The attack surface of a system that learns from data is fundamentally different from traditional software. We work both sides.
Sub-millisecond latency, distributed state, partition tolerance, event-driven architectures under high concurrency. The kind of requirements where theoretical correctness and production behavior diverge, and you need to know exactly why.
Fuzzers, scanners, OSINT pipelines, exploit PoCs, custom C2 infrastructure. When nothing off the shelf fits the threat model, we build it. We know how attackers think because we've written the tools.
GIL contention, asyncio event loop tuning, C extension boundaries, multiprocessing overhead, memory profiling in long-running processes. Python has hard limits. Working around them means knowing exactly where each one is and why it exists.
