Liberty Mutual, a major insurance group, is in the Spanish market (for info check out their website at
www.libertymutual.com. ) However, in your message you misspell "Seguros," the Spanish term used with insurance as "Saguros" and the word "security" does nothing but repeat an incorrect translation of "Seguros" in this context. You also provide no other contact details for this company.
From my experience, this appears to be a look-alike that is used to perpetrate various scams, from bogus lottery scams to advance fee scams. If the contact information is a phone number that starts with "34" (Country code for Spain) followed by a nine digit number begining with a "6," and or has an "Apartado Postal" (Post Office Box) address, it is most likely a scam.
