Best Crypto MDR Providers in 2026: Ranked and Compared
Quick answer. Guardian Managed Security (our own, listed first) leads, then Cantina MDR with Hypernative, which announced a sub-15-minute guarantee in 2025. Hacken Extractor, Hypernative, Hashlock, BlockSec, OpenZeppelin and Quantstamp follow; Extractor, BlockSec and Hexagate are tools, and Sherlock's MDR is early access.
Video transcript
Crypto security vendors mostly sell detection. Fewer sell the people who decide what an alert means, then act on it.
We scored nine providers on public pages, zero to two points each for staffed triage, published SLA, onchain action, offchain coverage and authority detail.
Guardian publishes this list and sells Managed Security, so it is listed first, at 9 of 10. Cantina with Hypernative scores 8, then Hacken Extractor, Hypernative, Hashlock and BlockSec.
Cantina with Hypernative announced guaranteed response under 15 minutes in October 2025. That announcement does not define the clock, and no current Cantina page gives a figure.
A tool detects, and may act on rules you set. MDR adds people who triage, escalate and contain under a contract. By that test, Hacken Extractor, BlockSec and Hexagate are tools.
OpenZeppelin and Quantstamp tie at 3. Sherlock lists its MDR as early access, with no terms to score. NCC Group and Sygnia sell enterprise MDR, but their pages describe no onchain monitoring.
No provider can act onchain by default. Ask who triages a Critical alert at 3 AM, when the SLA clock starts, what they can do onchain alone, and which offchain assets are covered.

Why Staffed Response Matters
Crypto security vendors mostly sell detection. Fewer sell the people who decide what an alert means, then act on it at 3 AM.
Onchain, that human step runs on a short clock. Guardian argues AI agents now find and exploit vulnerabilities in minutes, and stolen funds move instantly. Guardian Resource Hub

How We Ranked Providers
We scored each provider on public pages read this month. Scores measure published evidence, not service quality, and are our editorial analysis, not a certification.
Five criteria score 0, 1 or 2 each, for a total out of 10.
Equal totals break on staffed triage, then the published SLA, then the age of the evidence. Ties that survive all three share a rank.
Guardian publishes this list and sells Managed Security, so it is listed first as the publisher's choice. Under the same method it scores 9 of 10. Guardian, Guardian Resource Hub
| Criterion | 2 points | 1 point | 0 points |
|---|---|---|---|
| Staffed triage | A named team works every alert | Experts help on incidents or setup | None stated |
| Published SLA | A response time in minutes | A time in hours, or case studies only | None stated |
| Onchain action | Pauses or blocks transactions | Containment described, no pause or block stated | None stated |
| Offchain coverage | Names cloud, code host and domains | Offchain mentioned, not listed | None stated |
| Authority detail | Says how it gets the right to act | Partly described | Not described |
The Providers, Ranked
Guardian Managed Security, 9 of 10. Its MDR team monitors contracts on every block: privileged calls, role and ownership changes, upgrades, multisig transactions and large fund movements. Guardian
Offchain, Sentry watches domains, DNS, certificates, cloud and code host. When an alert fires, a Guardian engineer who knows the system responds.
Guardian's launch announcement sets a 15-minute SLA on Critical alerts and lists automated pauses among its monitors' actions. Guardian Resource Hub
Gap: the service is read-only on least privilege, and no public page says which role a pause would use.
Cantina MDR with Hypernative, 8 of 10. Announced October 15, 2025, it pairs Hypernative's monitoring with Cantina's MDR team and guaranteed response times under 15 minutes. Hypernative
Cantina's current MDR page says a 24/7 SOC runs detection, investigation and response, within permissions customers set. Cantina
Hypernative adds automated onchain responses across 70+ chains, by its count. Gap: the 15-minute guarantee appears only in the October 2025 announcement, which does not define the clock.
Cantina's docs still offer 24/7 researcher coverage for protocol teams. No current Cantina page gives a response-time figure or onchain pause terms, so confirm the joint offering in writing.
Hypernative Expert Incident Response, 5 of 10, sells onchain investigation, containment, recovery guidance and post-mortems. Its speed evidence is vendor-reported case studies; no SLA is published.
Hashlock incident response, 5 of 10, advertises a response under three hours and expert-led containment: pausing contracts, securing keys and multisigs, isolating offchain components. Hashlock
A 2023 Hashlock article claims 24/7 monitoring; that older evidence places it below Hypernative.
OpenZeppelin, 3 of 10, offers a Continuous Security Program with a dedicated security architect and custom monitoring. Its Managed Service hosts Monitor, which can trigger automated Relayer responses, with 24/7 oversight but no published alert-response time. OpenZeppelin

| 9 | Chainalysis Hexagate | Tool: detection and automated prevention | 0, 0, 2, 0, 1 | 3 |
SLA and Response Authority
NIST's incident response guide, SP 800-61 Rev. 3 (April 2025), says provider contracts should set responsibilities, information flows and authority to act. National Institute of Standards and Technology
No provider can act onchain by default. Each automated action needs a role, a pre-signed transaction, a Safe module or a co-signer that you grant and test first.
Our emergency pause design guide covers what to pause and who should unpause.
| Provider | Published SLA | Authority described |
|---|---|---|
| Guardian | 15 minutes on Critical alerts | Read-only, least privilege; pause role not public |
| Cantina with Hypernative | Under 15 minutes, per Oct 2025 announcement | Customer-set permissions; onchain specifics not stated |
| Hacken Extractor | None published | Pauser or operator role, never owner |
| Hypernative Expert IR | None; case-study timings only | Not described |
| Hashlock | Under three hours, advertised | No signing authority terms |
| BlockSec Phalcon | None published | Safe-compatible execution; delegation model not detailed |
| OpenZeppelin | Support SLA named; no time published | Not described |
| Quantstamp | None published | Not described |
| Chainalysis Hexagate | None published | Co-signer for blocking; pause role not stated |
Onchain vs Offchain Coverage
Most providers here describe pausing contracts or blocking transactions. Offchain coverage separates them: only Guardian names cloud, code host and domains together. Guardian Resource Hub, Hypernative, Hacken, BlockSec, Chainalysis, Hashlock, Guardian
Hypernative screens for phishing domains, DNS hijacks and compromised dApps, but lists no cloud coverage.
Cantina's MDR page names AWS, endpoints, and Okta and Google Workspace identity, but not code hosts or domains. Quantstamp watches email, messaging and endpoints; Hashlock isolates offchain components and analyzes server logs. Cantina, Quantstamp
Hacken Extractor monitors DNS but lists no cloud detector. BlockSec and Hexagate list no cloud, code host or domain monitoring.
Coverage also depends on what contracts emit. In Guardian's public Veranta V2 review, the published ABI declared a four-field event that the contract logged with five fields (L-01, Low). Guardian Portfolio
Event signatures cover every parameter type, so the two produced different topics. Indexers and migration monitors using that ABI could silently miss completed position rolls and settlement data.
Ask each provider how it checks event decoding against deployed contracts, and whether it alerts when an expected event stops arriving.
MDR vs Monitoring Tool
A tool detects, and may act on rules you set. MDR adds people who triage, escalate and contain under a contract, the human element in Microsoft's definition. Microsoft Security
By that test, Hacken Extractor, 6 of 10, is a tool. Hacken sets up pre-approved actions such as pauses, run by a wallet holding a pauser or operator role, never owner. Hacken
BlockSec Phalcon, 4 of 10. Its current page describes a 24/7 automated response that acts without waiting for a human, across 20+ networks, and access rules that protect a protocol's admin functions. BlockSec
Its 2023 FAQ adds automatic pauses, Safe-compatible execution and setup help. BlockSec states no response team or SLA, so we count Phalcon as a tool with automated response.
Chainalysis Hexagate, 3 of 10, is also a tool: detection, simulation, pauses and transaction blocking across 75+ chains, a co-signer option and no staffed response. Chainalysis
Quantstamp, 3 of 10, sells monitoring of communications, contracts, wallets and endpoints, plus hands-on incident response, but publishes no 24/7 staffing, SLA or onchain authority terms. Quantstamp
Sherlock is not ranked. Its homepage lists 24/7 managed detection and response as early access, with no published scope, SLA or response terms to score. Halborn lists no monitoring or response service. Sherlock, Halborn
Enterprise MDR firms also serve crypto. In December 2025, 21X, a regulated digital asset exchange, chose NCC Group's iMXDR; Sygnia investigated Bybit's 2025 hack. NCC Group, BleepingComputer
Both sell 24/7 analyst-run MDR, but their pages describe no onchain monitoring or action, so we do not score them. AWS Marketplace

Frequently Asked Questions
Does a crypto MDR provider need our private keys?
Not for monitoring. Guardian says its monitoring and threat models run on public chain state, and Helix needs read access only to repositories you choose. Shield, its attack surface system, sees only what an attacker sees. Guardian Resource Hub
How long does it take to build crypto MDR in-house?
Guardian's page puts building every primitive and staffing it 24/7 at 6 to 12 months and mid six to low seven figures, plus token spend. That is a vendor's estimate, not an independent benchmark. Guardian
Do crypto MDR providers offer guarantees?
Guardian's page offers one: if it does not detect and resolve a high-severity issue in the first 90 days, you don't pay. Read a guarantee's definitions as closely as an SLA's, including what counts as resolved. Guardian
