These include incident responders, security operation centre analysts who work in-house and at managed service providers.
The company's senior product marketing manager of Cyber Security Services, Artem Karasev, told a webinar on Tuesday that opening up the portal to a wider audience was part of the firm's efforts to "build a safer world".
“IT security teams in enterprises deal with numerous alerts every day. To find out which require detailed investigation or immediate response, specialists need context such as how widespread the suspicious object is, or where it originates from," he said.
All files that are uploaded to the portal will be analysed using advanced threat detection technologies such as heuristic analysis and Kaspersky Cloud Sandbox, to monitor the behaviour and actions of the file in question. The basic threat information provided would be sufficient for a user to determine which files posed a genuine threat and prioritise incidents based on risk level.
The sandbox is based on Kaspersky's proprietary and patented technology, which is used internally and allows it to detect more than 346,000 new malicious objects every day.
The access provided has its limits: a user can upload any number of files to check with look-ups for URL, hash or IP, with a limit of 100 requests a day.
Those who buy a full commercial license, will have additional premium functionality, including access to detailed Threat Lookup and Cloud Sandbox reports, APT (advanced persistent threat or nation-state actors) Intelligence and Financial Threat Intelligence Reporting and Sandbox for URLs.
Karasev said the company planned to develop advanced APT detection, static analysis and other portal features at a later date.
A survey by the company had found that only 36% of businesses were using threat intelligence services, with about 31% planning to use one in the next 12 months. The main barrier standing in the way of wider use was the cost, Kaspersky claimed.
"Whenever SOC analysts find a suspicious threat indicator, whether it be a file, file hash, IP address or URL, they can now check it on the Kaspersky Threat Intelligence Portal. The portal will then determine if it is malicious, as well as provide information on how widespread the threat is," the company said.
"It also presents analysts with names the threat has previously been detected under, details of organisations which have registered a suspicious web resource, the date the domain was created and when the file was seen for the first and last time, among other information."
Kaspersky has been in the security and anti-virus business since 1997.
