Of the new “Easy Guardian” product, Acme Fox creator David Cantaluppi, whose company is now called “KDev,” writes, “Easy Guardian brings together the powerful tools of the open source arena: NMAP and Net-SNMP in a small silent Linux embedded box. The on-board GSM/GPRS Quad Band modem is linked to an advanced scanning engine that will alert you with a SMS every time a threshold exceed is detected on your services and network devices.”
