Multi-C2 Network Pivot Bridge Tool
A standalone network pivoting toolkit that operates independently of any single C2 framework, providing bind listeners and relay chains across SMB, TCP, HTTP, and named pipes. Red teamers can deploy it alongside their existing C2 of choice (Sliver, Mythic, Havoc) without replacing their workflow.
Why this matters
You are a red teamer who uses different C2 frameworks depending on the engagement. When you encounter a machine that only accepts inbound SMB, your primary C2 cannot establish a bind pivot. You have tried standalone tunneling tools, but they lack the OPSEC features and protocol flexibility needed for professional engagements. You want a universal pivoting layer that sits between your C2 and the target network, handling bind connections and relay chains regardless of which C2 framework you are running. Today, you cobble together multiple tools and custom scripts, wasting valuable engagement time.
- · Built for Red team operators and penetration testers who use multiple C2 frameworks and need a universal pivoting layer that works across restricted network environments regardless of their primary C2 tool.
- · Most likely monetization: Annual license per seat with tiered features.

MVP Scope · 1–2 weeks
- Survey existing open-source tunneling tools (Chisel, Ligolo-ng, Plink) to identify feature gaps in bind SMB support
- Design the relay agent architecture — how it accepts inbound connections and forwards to an external C2 listener
- Prototype a minimal Go-based agent that creates an SMB named pipe listener and forwards connections to a configurable endpoint
- Set up a lab environment simulating inbound-only SMB restriction for testing
- Write a technical blog post outlining the problem and the proposed solution to gauge community interest
- Implement TCP and HTTP bind listeners alongside the SMB prototype
- Build the relay configuration interface — YAML or CLI-based for defining pivot chains
- Test forwarding traffic from the bind listener to a Sliver and Mythic C2 listener to prove C2-agnosticism
- Add basic encryption and authentication to the relay channel for OPSEC
- Distribute the prototype to 5-10 trusted red team contacts for real-world testing feedback
Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1Existing free tools like Ligolo-ng and Chisel already handle many pivoting scenarios and are rapidly improving — users may not see enough incremental value to pay for a commercial alternative
- 2The C2-agnostic design requires maintaining compatibility with multiple frameworks' communication protocols, creating ongoing engineering overhead that a small team cannot sustain
- 3Security teams may be reluctant to introduce a third-party pivoting tool into their engagement stack due to trust and OPSEC concerns — they need to fully understand and audit any tool that handles C2 traffic
Evidence Summary
How AI synthesized this insight — no verbatim quotes
The discussion highlights a specific pivoting gap in a single C2 framework, but the underlying problem — restricted networks requiring bind connections — is framework-agnostic. Multiple commenters express ongoing need with no resolution, and the maintainer's acknowledgment of bandwidth constraints suggests the open-source ecosystem cannot fill this gap quickly. A standalone tool that solves the problem across C2 platforms could address a broader audience, though competition from existing free tunneling tools presents a meaningful challenge to monetization.

Multi-C2 Network Pivot Bridge Tool
Sub-headline
A standalone network pivoting toolkit that operates independently of any single C2 framework, providing bind listeners and relay chains across SMB, TCP, HTTP, and named pipes. Red teamers can deploy it alongside their existing C2 of choice (Sliver, Mythic, Havoc) without replacing their workflow.
Who It's For
For Red team operators and penetration testers who use multiple C2 frameworks and need a universal pivoting layer that works across restricted network environments regardless of their primary C2 tool
Feature List
✓ Protocol-agnostic bind listeners (SMB, TCP, HTTP, named pipes) ✓ Multi-hop relay chaining with automatic failover ✓ C2-agnostic relay agent that forwards traffic to any external C2 listener ✓ OPSEC configuration profiles for different engagement scenarios ✓ Cross-platform agent support (Windows, Linux, macOS)
