About

Prime Dev Force Security checks a website's security setup from the outside and tells you what to fix first. Enter a domain you own and in about 3–15 seconds you get results for HTTPS and redirects, TLS certificates, security headers, DNS, and email authentication (SPF, DKIM and DMARC). Every finding shows the evidence behind it, a severity and confidence rating, and step-by-step fix instructions, ordered into a prioritized task list. The free check needs no account. Pro ($12/month) adds daily monitoring, alerts and a server agent for sites you own. Agency ($49/month) covers up to 30 client domains with branded client reports. It is an outside-in configuration check: it is not a penetration test and does not scan pages behind a login.

About

SMTP Senpai is MailSenpai's EU-hosted SMTP relay and REST email API for password resets, order confirmations, notifications and website forms. Connect via SMTP on port 2525 or 587 with STARTTLS, the REST API, or a form endpoint for static sites. DKIM signing uses your verified sender domain, with SPF/DKIM/DMARC checks and automatic suppression of bounced addresses. The permanent free plan includes 5,000 emails per calendar month, up to 200 per day and 30 in the preceding hour, one verified sender domain and 7-day sending logs. No card or expiry. Paid annual plans start at EUR 12.90 per month plus VAT for 10,000 emails per month and 90-day logs. An email report is sent weekly on Monday. Official WordPress and Drupal plugins and open-source SDKs support integration. Written support is available in English and Italian. MailSenpai is the separate newsletter and email marketing platform.
