If you own at least one ASN and want visibility of your IPs' reputation across your network, it's time to register for the Spamhaus Reputation Portal.
From a simple-to-read dashboard outlining how many listings you have on Spamhaus' blocklists, to a ticket center to handle removal requests, the Portal makes managing and resolving listings effortless. Add to this automated updates of newly listed IPs, and this tool enables you to approach your network's reputation proactively.
For a quick tour, keep reading or watch this short video.
This provides you with an overview of your network. It includes the number of ranges you have associated with your account, and the total number of listings for those ranges by each IP blocklist:
The dashboard also provides you with the percentage change in the number of listings for each blocklist across 30 days.
For quick reference, several “top tens” show the most recently listed IPs, the longest listed IPs, and your most abused /24s.
This area lists all your ranges by /24, along with the number of SBL, XBL, CSS, and BCL listings. All the information is fully sortable and can be exported, should you require. From this page, you can quickly navigate to a heatmap of a specific /24.
The heatmap shows the individual IPs within a /24 and displays which have SBL, CSS, BCL, or XBL listings associated with them. From here, you can click on one of the IPs to review the complete listing information.
Currently, it isn’t possible to request removal from the SBL – the usual process of the ISP contacting the SBL team via email remains in place. However, for the other blocklists, once you have taken the relevant remediation that caused the listing in the first place, you can request removal.
Here you can track all your requests and communications with the Spamhaus team. This includes adding or deleting ranges from your network, changing user details, or working with the team to resolve a listing issue.
To save you from logging into the portal daily, you can choose to receive reputation updates via email or our API, providing automatic updates of new listings.
We hope you get value from this newly released tool, and look forward to increasing its functionality in the not too distant future.

This quarter botnet C&C activity reduced slightly, and operators within the LatAm region appeared to be getting control of newly observed botnet C&C abuse, but two well-known global network operators struggled to get to grips with continuing abuse.

In our experience, residential proxies are an often overlooked security threat; one that can be very difficult to remediate for the end user who -in our experience- is entirely unaware of its existence.
