Btw the above applies to hi-sec activities. As for hauling into and through lowsec there are several approaches.
You can use a sub 2 sec align time ship to haul lesser quantities of stuff such as modules, ammo and alike. The Sunesis can be fit to be able to haul a fairly good amount of cargo (600 m³ native) and still align under 2 sec and can do so with minimal skill training if any, see below.
If you only use it for hauling you can alter the fit accordingly or just remove what is not needed to reduce its price.
It is almost impossible to catch a sub 2 sec ship in lowsec if you just warp from gate to gate or to station, though it is still possible under specific circumstances which are usually rare to occur. You can use a cheap sub 2 sec align frigate to scout ahead and if everything seems fine you can go with the hauler. Same applies to moving ships through, first scout then if things look okay you might go for it.
By scouting ahead though more risky you could even use haulers that are not under 2 seconds align time though people can camp the gate by the time you arrive so that is always great additional risk.
Ships you can not fit into the Sunesis obviously so you might just fit them for tank (shield extenders for example) and as many warp core stabilizers in the lows as possible, the more warp stabs you have the less chance the gate campers have enough scrams / points to prevent your warp and if you scout ahead in a cheap sub 2 sec frigate you might see how much if any opposition you might face at the moment.
For the station you want to dock in and out of you will need instadock and at several distances insta-undock / instawarp bookmarks (preferably at 5000+ km up to 10K or more at several very different distances) so you can dock up safely and get away safely as well in case someone camps the station. You can read about these and other stuff I mention at the EVE University wiki so won’t go into detail about such here to keep things as short as possible.
Another approach could be though costs ISK is to post hauling contracts so others take the risk in exchange for ISK and haul your stuff to the station of your choice from hi-sec. More efficient if you contract more stuff at once rarely with a proper collateral than to make several contracts more often with less stuff and probably cheaper too that way I guess.
Also if you are Omega you can use the cloak+mwd trick with properly fit haulers people say it is fairly reliable and fairly “safe” so you might read upon that as well if you can use cloaking devices.
Probably other methods and details too but this is what came to mind quickly, hope this helps.
