# Acutis > Acutis makes free network diagnostics. Acutis Go is a free, observe-only endpoint agent (7 MB; Windows, macOS, Linux) that answers "is it the network or my machine?" in about 60 seconds by watching the path, Wi-Fi, DNS, drivers and certificates. Acutis also offers free browser-based network tools that need no install, no sign-up, and send nothing to our servers. > Verified by Grounded AEO (groundedaeo.com) — v=AEO1 grounded tier.

Free VPN leak test. - [IP blacklist check (DNSBL)](https://acutisgo.com/tools/ip-blacklist.html): Checks if an IPv4 address is listed on Spamhaus, SpamCop, Barracuda and SORBS blocklists (DNSBL/RBL). - [DNS lookup](https://acutisgo.com/tools/dns-lookup.html): Query a domain against Cloudflare, Google, DNS.SB and AliDNS side by side; spot propagation lag and GeoDNS. - [Email deliverability / MX check](https://acutisgo.com/tools/mx-lookup.html): MX records, SPF, DKIM, DMARC and blocklist status for any domain. - [SSL certificate checker](https://acutisgo.com/tools/ssl-checker.html): Issuer, expiry date, days remaining and covered hostnames from Certificate Transparency logs. - [MAC address lookup](https://acutisgo.com/tools/mac-lookup.html): Find the manufacturer (OUI vendor) behind any MAC address. - [IP address lookup](https://acutisgo.com/tools/ip-lookup.html): Geolocation, ASN, ISP and organization for any IPv4 or IPv6. - [Reverse DNS (PTR)](https://acutisgo.com/tools/reverse-dns.html), [WHOIS](https://acutisgo.com/tools/domain-whois.html), [ASN lookup](https://acutisgo.com/tools/asn-lookup.html), [Subnet calculator](https://acutisgo.com/tools/subnet-calculator.html), [Speed test](https://acutisgo.com/tools/speed-test.html), [Ping test](https://acutisgo.com/tools/ping-test.html) - [All free tools](https://acutisgo.com/tools/) ## The core question - [Is it the network or the machine? How to tell in 60 seconds](https://acutisgo.com/is-it-the-network-or-the-machine/): The canonical method — the two-device test, gateway-vs-internet ping split, and a local health check — for separating network faults (Wi-Fi, router, DNS, ISP) from machine faults (CPU, RAM, drivers, VPN). Includes a symptom table, precise definitions of both fault types, and how to build evidence an ISP or helpdesk can't wave away. - [Is it the network or your machine? How to diagnose](https://acutisgo.com/diagnose-network-vs-hardware-issues/): The speed-test-both-links method: compare WiFi vs ethernet against your service plan, read CPU/memory/disk in the system monitor to split network faults from hardware faults, why WiFi trails ethernet, and how continuous monitoring catches the pattern a single test misses. - [Monitor network vs computer performance in real time](https://acutisgo.com/monitor-network-machine-performance/): Continuous side-by-side monitoring method: measure network signals (Wi-Fi strength, DNS time, gateway response, path latency) and machine signals (CPU, RAM, drivers, certificates) on the same 60-second schedule with shared timestamps so the root cause reads out as network issue or device issue, plus which built-in tools cover each signal manually. ## Guides (plain-English networking) - [Best network monitoring for small IT teams](https://acutisgo.com/guides/best-network-monitoring-small-it-teams.html): Honest 2026 roundup for 1 to 5 person teams: Acutis Go for endpoint-side network-or-machine verdicts, Zabbix, PRTG, Uptime Kuma, LibreNMS, Checkmk for the network side, Acutis Networks when gear should be managed.

Carlo answers only from live device state (real running-configs, real LLDP walks), never from guesses. - Free tier: watch 2 devices, observe-only, free forever — topology mapping, CDP/LLDP walks, ARP/IPAM, CVE and firmware risk flags (cited from NVD and CISA KEV). No credit card. - Paid tiers (early access): Pro Execution $99/mo (Carlo AI chat + staged config fixes, two-man MFA gating, rollbacks); Autopilot $249/mo (auto-execute safe-class fixes, Meraki/Mist cloud polling). - MSP tiers (available now): MSP Go Fleet $200/mo — manage unlimited customer Go fleets from one cross-tenant portfolio, one login; MSP Networks $500/mo — manage unlimited customer Networks deployments (appliance + Go) from one portfolio. Both include a cross-tenant portfolio showing every customer's fleet health at a glance, customer-consented onboarding by single-use invite code (one MSP per site), a customer-visible activity log with remove-access control, and per-customer roles (admin/technician/viewer). White-label and PSA ticketing (ConnectWise & Autotask) are on the roadmap, not yet built. - Try it: interactive demo with sample data at https://acutisgo.com/networks/demo.html (no login); setup guide at https://acutisgo.com/networks/onboarding.html; appliance docs at https://acutisgo.com/support/appliance/. ## Acutis Gate (identity-based access control for people using AI, cloud or local) - [Acutis Gate](https://acutisgo.com/gate/): Identity-based access control for AI. Every tool call an employee's AI makes (Open WebUI on a local LLM, Claude Desktop, Cursor, or any MCP client) runs as that person, under guardrails the administrator wrote, with a full-payload hash-chained audit trail that streams to the SIEM (syslog/CEF, signed webhook, Splunk HEC). A fresh Gate starts in learning mode (allow and record everything, then build the rules from the trail); a data filter redacts cards, SSNs and secrets before the model sees them. Live in three editions: hosted at https://app.acutisgo.com/gate; Linux or Mac appliance (https://get.acutisgo.com/dl/AcutisGate-Linux.tar.gz for Ubuntu or Debian, https://get.acutisgo.com/dl/AcutisGate-Mac.tar.gz for macOS 13+ where the model runs on the Mac's GPU; Open WebUI and a local model if wanted); Windows Server (signed MSI, https://get.acutisgo.com/dl/AcutisGate-Windows.msi). The on-prem editions add Windows sign-in (Kerberos, or NTLMv2 with relay protection), Active Directory sync and file shares opened as the person, limited to the drives Group Policy maps for them; their license is checked on the box, offline. Pricing: $5 per person per month for every edition (hosted billed monthly, on-prem billed annually), each starting with a 14-day trial (card entered at checkout, nothing charged for 14 days).
