Technically, though the higher the total hash rate the more secure in general. To get more specific, yes one would need to know who is responsible for how much hash rate to get a clearer picture of the decentralization.

It isn't secure at all if... 

1. one pool has more than 50% of the total network hashing power.
2. two largest mining pools have more than 33.3% each.
3. three largest mining pools have more than 25% each.
4. four largest mining pools have more than 20% each.

This is because relative hashing power is more important than total hashing power... 100% is essentially hashing power of largest mining pool, not the total network hashing power.

If one of the larger mining pools go offline or cause network to split as two alternate chains, all the other mining pools have to be able to compensate.

Luckily things are getting more decentralized as opposed to less...
