The threat of infected attachments is skyrocketing
Email attacks remain the primary vector for breaches. Manually verifying every received file is impossible given daily volumes. Traditional security solutions often miss novel threats or require complex maintenance.
Main negative impacts:
Insufficient analysis time
Security teams are overwhelmed by alerts, leading to critical delays in response during real incidents.
High phishing risk
A single undetected malicious file can compromise your entire information system.
IT team burnout
Manual threat handling prevents security experts from focusing on high-value tasks.
Swiftask integrates CIRCL Hash Lookup to automatically verify the hash of every attachment. The AI decides instantly whether to block, isolate, or allow the email.
BEFORE / AFTER
What changes with Swiftask
Manual and reactive analysis
An employee receives a suspicious email. They report it to IT. The analyst downloads the attachment, calculates the hash, and manually consults threat databases. By the time the threat is confirmed, it has often already been opened by others.
Automated analysis with Swiftask
Upon receiving the email, Swiftask extracts the attachment's hash. It instantly queries CIRCL Hash Lookup. If a match is found, the email is moved to quarantine and the security team is alerted in under a second.
Deploy your security filter in 4 steps
1
STEP 1 : Configure the connector
Integrate CIRCL Hash Lookup into Swiftask to enable automatic querying of the threat database.
2
STEP 2 : Define filtering rules
Configure risk thresholds and actions (block, alert, isolate) based on the lookup results.
3
STEP 3 : Automate the email flow
Connect your mail server to Swiftask so that every attachment is analyzed the moment it is received.
4
STEP 4 : Monitoring and audit
Track all blocked intrusion attempts via the Swiftask dashboard and adjust alert sensitivity as needed.
Advanced detection capabilities
Swiftask analyzes file hashes, sender context, and email body content for a multi-layered detection approach.
- Target connector: The agent performs the right actions in circl hash lookup based on event context.
- Automated actions: Automatic hash extraction (MD5, SHA-1, SHA-256). Real-time comparison with the CIRCL database. Automatic actions on infected emails. Incident reports generated automatically for the SOC.
- Native governance: The integration ensures high availability and fast response, which is essential for countering Zero-Day attacks.
Each action is contextualized and executed automatically at the right time.
Each Swiftask agent uses a dedicated identity (e.g. agent-circl-hash-lookup@swiftask.ai ). You keep full visibility on every action and every sent message.
Key takeaway: The agent automates repetitive decisions and leaves high-value actions to your teams.
Operational benefits for security
