The bottom line
A focused exposure monitor, but IP caps and alerts that need verification temper its value.
Shodan Monitor tracks devices and services accessible from the internet within your network range, with notifications when something unexpected appears. The pricing page lists a free plan for basic Shodan access, a $49 one-time Membership upgrade monitoring 16 IPs, and Freelancer at $69/month for up to 5,120 IPs per month. Annual prices are not published.
The limits matter: Freelancer and Small Business each list one user, while higher IP counts cost more or require custom Enterprise pricing. In one Reddit thread, a user investigated recurring results that appeared inaccurate and traced them to a stale static route. That is a reminder to validate alerts against your network before treating them as confirmed exposure; the thread is not enough to establish how often this happens.

01What Shodan Monitor actually does
Shodan Monitor tracks devices and services in a network range that are accessible directly from the internet. Shodan says it can send real-time notifications when something unexpected appears. The point is to give network owners visibility into exposed systems, rather than to monitor activity inside their network.
Shodan says it crawls the entire internet every week. Monitor uses that visibility to show exposed devices and services in the ranges you track; the product also supports network discovery. Developers can use Shodan’s API for IP lookups, searches and data streaming.
Pricing is split across several plans. The Free Plan is listed at $0 per month with basic API access and limited search results, but its listed inclusions do not specify monitored IPs. Membership costs $49 as a one-time account upgrade and includes monitoring for 16 IPs. Paid monthly plans start at $69 for Freelancer, which includes monitoring and scanning for up to 5,120 IPs per month. Annual prices are not published.
02Where Shodan Monitor is strong
Shodan Monitor is useful when the question is simple: which systems in our range can someone reach from the public internet? It puts exposed devices and services into one view, and Shodan says it sends real-time alerts when something unexpected appears. That can help teams spot an exposure without waiting for a manual check of every address.
The plan limits make the product’s scale easier to judge before buying:
- Membership is a $49 one-time account upgrade and includes monitoring for 16 IPs, plus 100 scan credits and 100 query credits per month.
- Freelancer costs $69 per month and includes monitoring and scanning for up to 5,120 IPs per month.
- Small Business costs $359 per month and lists up to 65,536 IPs per month.
- Corporate costs $1,099 per month and lists up to 327,680 IPs per month.
Shodan also says it crawls the entire internet weekly, and its API supports IP lookups, searches and data streaming. For teams already using Shodan’s search and API tools, Monitor fits into the same service rather than requiring a separate discovery workflow. The published limits provide a useful starting point for matching the bill to the size of the ranges being watched.
03Where it falls short
The alert is a lead to investigate, not proof that a device is currently reachable. In one Reddit thread, a Shodan Monitor user reported repeated results for apparently unused IPs on ports 8008 and 8010. Manual checks found no response; the user later traced the results to a lingering static route to a legacy product. That example does not establish how often false positives occur, but it shows why alerts may need network-side verification.
The IP caps can also make costs jump quickly. Membership covers only 16 IPs; Freelancer lists up to 5,120 IPs per month for $69, while Small Business is $359 for up to 65,536. Corporate costs $1,099 and lists up to 327,680. Enterprise pricing is custom, though the plan lists unlimited monitored IPs. Each of the named paid plans lists one user, so teams should confirm whether that fits their access needs. Annual prices are not published, and the Free Plan’s listed features do not include a monitoring allowance. Shodan also does not publish a free-trial term in the published pricing details.
04Shodan Monitor pricing: what you'll actually pay
Shodan lists a free plan with one user, basic API access and limited search results. Membership costs $49 once per account and includes monitoring for 16 IPs, 100 scan credits and 100 query credits per month. It is not a monthly subscription tier.
The lowest paid monthly plan is Freelancer at $69, with one user and monitoring and scanning for up to 5,120 IPs per month. Small Business jumps to $359 per month—$290 more, or over five times the price—for up to 65,536 IPs. Corporate is $1,099 per month and covers up to 327,680 IPs; Enterprise pricing is custom, with unlimited monitored IPs listed.
The pricing page lists no add-ons. Annual prices are not published, so there is no stated annual discount to compare. Freelancer, Small Business and Corporate each include one user; teams needing more should check Enterprise terms. Shodan says alerts are real-time, but buyers should verify alert behavior before treating them as proof of exposure.
05Switching to (or from) Shodan Monitor
Switching in means defining which IP ranges to monitor and checking that the plan’s limits fit: Membership covers 16 IPs, Freelancer up to 5,120, Small Business up to 65,536, and Corporate up to 327,680. Shodan describes Monitor as showing internet-accessible devices and sending real-time notifications. The published material does not specify a migration tool, data-export format, retention period or alert-delivery details, so confirm those before moving operational workflows.
Switching out may be harder if your team depends on Shodan search or API access, but the published information does not establish what data can be exported or how portable saved work is. The one-user caps on the listed paid tiers may also be a mismatch for teams that need shared access. We can’t responsibly say what tends to make people leave per Reddit: no Reddit posts were included in the published material, so there is no supported account of common complaints or churn reasons.
From the threadsWhat users say
The small number of user reports shows both concern about unexpected results and the work needed to check them. In one thread, the reported access was eventually traced to a stale static route; another user liked Monitor’s history and web interface.
I'm getting some strange results that are potentially false positives but are concerning me slightly
Nope I get nothing back, even tried a full Nmap scan
A static route for the affected IP's still existed from the Fortigate to a legacy product which use to act as the gateway when these IP's were still in use
It'd just be nice to have features like history and and nice web interface, like Shodan Monitor has
Questions people ask
What does Shodan Monitor track?
Shodan Monitor tracks devices and services in a network range that are directly accessible from the internet. Shodan describes its features as exposure monitoring, service visibility, and network discovery. It also offers a developer API for IP lookups, searching, and data streaming.
How often does it scan, and does it send alerts?
Shodan says it crawls the entire internet every week and can provide real-time notifications when something unexpected appears. The available information does not specify the exact alerting conditions or guarantee that every change will trigger an immediate notification, so confirm those details with Shodan if timing is critical.
How much does Shodan Monitor cost?
The listed paid monthly plans start at $69 for Freelancer. Small Business is $359 per month, and Corporate is $1,099 per month. Membership is a $49 one-time account upgrade; the Free Plan costs $0. Annual prices are not published, and Enterprise pricing is custom.
How many IPs can each plan monitor?
Membership includes monitoring for 16 IPs. Freelancer lists up to 5,120 IPs per month, Small Business up to 65,536, and Corporate up to 327,680. Enterprise lists unlimited monitored IPs. The Free Plan’s monitoring allowance is not published, so don’t assume it includes monitoring.
Can Monitor report an IP as exposed when it is not actually in use?
One Reddit user could not reproduce reported access with a browser or Nmap scan, then traced the result to a static route still pointing to a legacy product. That account shows why a finding may need investigation; it does not establish how often Shodan reports inaccurate results.
