Five thousand times apart, and not one publishes a denominator

Decision guide

What matters most before choosing in this category

The right monitoring platform depends on what you need to happen at the moment of detection. Alerting a human at 3am and automatically pausing a contract are different products, and the gap between them is most of the value. Catches are counted only when named, dated and evidenced as acting before or during the exploit — a post-mortem published after the funds moved is analysis, not detection. Treat the advertised false-positive rates with scepticism: they span five thousand times across this pool for products solving the same problem, and none carries a denominator.

Key question

At detection, do you need an alert, an automated contract pause, or pre-inclusion blocking?

Key question

Who is awake to act on an alert, and how fast can they actually reach the pause?

Key question

Can the vendor name a dated incident where its system acted before the funds moved?

Default starting point

BlockSec Phalcon

Attack detection that front-runs the exploit transaction to block it

Data checked Aug 2026

Attack detection that front-runs the exploit transaction to block it. Strongest on what it can actually do (10/10): The strongest actual capability here: it uses "a gas-bidding strategy" to "place our transaction on the chain ahead of the attack's to block the hack before it can be executed", plus automatic protocol pauses and automatic LP withdrawals, executing "within one block time" via Safe{Wallet}-compatible authorised… Weakest on pricing and procurement disclosure (3/10): No price on the product page, and the product has moved to invite-only access, which removes even self-serve price discovery. Scores above the floor because BlockSec has separately confirmed the commercial shape — SaaS subscription, card or crypto payment — rather than pure enterprise opacity. Published price: Not published. The product page describes Phalcon as "exclusive, invite-only", directing users to "book a demo". No price appears on any BlockSec page loaded; figures circulating elsewhere ($1,200–$7,100/month) appear only in third-party write-ups.

Best for

What it can actually DO — 10/10False-positive honesty and detection method — 8/10

Main tradeoff

Its published record stops at January 2024 and its false-positive disclosure dates to December 2023 — and front-running an attacker requires granting pre-authorised transaction execution rights, which is a real custody decision, not a config toggle.

Hypernative

Behavioural threat detection with automated contract pausing for protocols

Behavioural threat detection with automated contract pausing for protocols. Strongest on verified pre-emptive catches (9/10): Publishes eight named incidents with amounts (Balancer V2 $19.3M, Solv $10M, Venus $13M, Parallel $1.52M, Kinetic $5M, SparkDEX $1.5M). The Balancer case is independently corroborated: on 3 Nov 2025 its monitoring flagged the exploit and CSPv6 pools were auto-paused across affected networks, protecting $19.3M. But the… Weakest on pricing and procurement disclosure (1/10): No pricing artefact of any kind. The /pricing path 404s, and the homepage carries only "Request a Demo" — no tier names, no ranges, no unit of billing, no indication whether pricing is per-chain, per-contract or per-TVL. Published price: Not published. No pricing page exists — hypernative.io/pricing returns HTTP 404. The only call-to-action on the site is "Request a Demo".

Best for: Verified pre-emptive catches — 9/10

Hexagate (by Chainalysis)

Machine-learning threat detection with contract pause and transaction blocking

Machine-learning threat detection with contract pause and transaction blocking. Strongest on what it can actually do (8/10): Product page states it can "trigger automated actions like contract pauses, transaction blocking" alongside detection. It cites that "less than 2% of projects responded to attacks within the first hour", which is the gap automation is sold to close — but no published latency figure between malicious transaction and… Weakest on pricing and procurement disclosure (1/10): No price on the Hexagate product page, and no standalone Hexagate pricing page — it is now a Chainalysis SKU sold under enterprise procurement, so a buyer cannot even establish an order of magnitude before entering a sales cycle. Published price: Not published. The Chainalysis Hexagate product page lists no price, tier, range or unit of billing; access is via Chainalysis enterprise sales.

Frequently asked

Questions people ask before choosing on-chain monitoring

Can I trust a published false-positive rate?

Not as stated. This pool advertises rates from under 0.0002% to around 1% — a five-thousand-fold spread for products solving the same problem — and not one publishes a denominator, a time window or a methodology. The rate is shown here and scored on whether it is checkable, never on how impressive it looks.

Do these products actually stop exploits?

Sometimes, and the honest answer is that the evidence is thinner than the marketing. The default free entry point for most teams into this category has been shut down entirely, and one named vendor left the market after its own risk agent fed inaccurate data into a lending protocol — the exact failure this category exists to prevent.

What matters most when picking a monitoring platform?

Dated, evidenced catches and what the product can do at detection — 65% of the weight between them. A platform that only alerts is a different purchase from one that can pause a contract.
