It all started with an idea...

or Guardanty or Guarranty = Guard(ing) and Guarantee/Guaranty

or Alternatives with 'IT' (instead of Guard, Sentry, Lock, etc):
ITmorrow or MorrowIT (Morrow = Tomorrow, Future, Next; Innovative, etc);
or NewanIT (= New and An and IT = Innovative IT Solutions);
or FitmaxIT or BizmaxIT or NeomaxIT or PlusmaxIT (= Fit, Professional or New/Innovative and Maximum IT Solutions/Services)

= Professional and Technology and Star (Also 'Protech' reminds Protect=Security.)

or Protectsia or Securitsia = Security Solutions Center

resonance is not pleasant

Rex = Leader, First, etc;
or DefendChamp(s);
or KeeperRex or KeeperChamp(s);
or DenyRex;
or ProtectRex

resonance is not pleasant

or SafeguardWings
or Guard(ing)Realm or SentryRealm

Hello, can you make the contest guaranted and private (for closed/hidden-entries to others)?.. Good works.

= Smart/Innovative Safety Solutions

= Leader (IT-)Security Solutions;
or SentryKing or KingSentry;
or SentryMaxi (Maximum Security);
or GuardChamp(s)

= New and A and Security

or OptLock (Apt = Ideal, Fit, etc and/or Smart, Technological, etc)

Cool but resonance is not good ... It's very important domain name has a good sound :P

or LockApt or LockOpt

or Consulock(ing) = Consulting and Lock(ing)

= Professional (e-)Guard Center/Supplier

or SentryPrime or SentryPremium
or GuardUltra or SentryUltra

Could you please more explain "Sentryum" ?

Sentry = Guard, Keeper, Security, etc;
-um/-ium = Center, Place, etc;
Sentryum [Sentriyum] = Security Solutions Center, Security Consulting Services, etc

sentrium is already taken... too bad for me

sentrium.com is inactive;
also sentrium.co or sentrium.co.uk or 'sentrium.it' is available;
you can buy these alternatives.

or AptSentry or OptSentry (Apt/Opt = Ideal, Fit, Optimum, etc; and/or Smart, Technological, etc)

or SentryApt or SentryOpt

or Securitechie = Technological Security Services/Solutions

Preferred names would be shorter in length. Prefer one word (3 syllables). Mashups of words to form a meaningful name are also a plus.
However, multiple words that can be shortened to good acronyms are also welcome.
It's very important domain name has a good sound :P

Other Suggestions:
Secuite or SentryTeam = Security and Suite (Security Solutions);
or PallySecure or PallySecurity

= Cyber and Guardian

not too bad :P #more
